Slackware :: Can't Install From DVD With AHCI Enabled?
May 12, 2011
I'm doing a clean install on a new machine, and when I tried to boot the install DVD, ISOLinux gave me the following error:
Code:
Could not find kernel image: linux After some experimentation, I found that switching the SATA mode in the BIOS from AHCI to Native IDE solved the problem and installation is proceeding normally.
However, I want AHCI enabled. (I think, unless someone has a compelling reason why I shouldn't.) My web-searching suggests that if the system is installed in IDE mode, it won't boot if I switch to AHCI afterwards. Is this a common problem? Is there a workaround? Is it a motherboard issue?

I have been running a dual-boot, Windows 7 and Ubuntu 10.10 system with the disks set for IDE with no problems. I have just attempted to change the disk system to AHCI and, whilst I can boot into Windows 7, I am unable to boot into Linux and get the error: "Alert! /dev/disk/by-uuid/5d773307-a046-40fa-ba29-728611bc7eed does not exist" I am new to Linux so am unsure where to go from here. I have reverted to IDE for the moment and it boots Ok.

Do I need to add any special options to mkinitrd for AHCI configuration?
mkinitrd -c -k 2.6.37.6-smp -m ext4
Does it know I'm not in legacy PATA mode or do I have to add something to load AHCI module with it?

I am using openSuSE 11.2 on a VGN-AR41L. I have also erased the preinstalled Home Vista (what a pleasure). Now to my problem. My system boots correctly but if I press the <ESC> key while booting I can see the following messages:
"Doing fast boot
FATAL: mbcache module not found
FATAL: ahci module not found
"
and the boot process continues normally.
Why this happens? Does this mean that I have a problem that I haven't discovered yet? Is it something that I can ignore? I am using SUSE Linux from version SUSE Linux 8 personal and although I am not a power user I have done my two desertions on this system and I am very happy with SUSE. I have bought SUSE Linux 8 Personal and SUSE Linux 10 all the other versions until today have been downloaded.

Today I stumbled upon Magic_SysRq_key. Basically, it's allows the user to perform various low level commands regardless of the system's statee.g.Alt+SysRq+b will reboot the system without syncing or unmounting.(SysRq is Print on most systems.)I see the point the use for kernel hackers and such, which compile their own kernels anyway, but why is this enabled by default?

I've been playing around with browsers today and just for kicks I'm trying to figure out how I get webkit enabled in konqueor. Has anyone got this to work? I've done a lot of googling, but haven't gotten anything to work yet.

Just wondering now I see computers everywhere with 6G of ram or more if the new 32b kernels are going to be setup for large amounts of ram or will they still need to be recompiled? Also will there be better ssd support for things like "trim"? I know you edit the fstab to get the Linux version of trim but I am just wondering if stuff like that will just be automatic or if I will continue to need to tweak. I like to tweak but sometimes its the lack of need for tweaking that makes me like slack.

I updated to latest -current last night and since then have not been able to login to my KDE desktop. After typing in the password, I get the starter icons come up, and just as the last one comes up, the desktop logs out to the login screen again. I worked out that it was because desktop effects were enabled - disabling these in kwinrc allows me to login, although without desktop effects.Using NVidia 256.53 binary drivers b.t.w.

When I plug the webcam in (usb), the led starts to shine, indicating that it is filming. When I use a program (XSane for example) and click the 'scan' button, the led turns off! It seems that the cam works when it shouldn't, and vice versa.

Been thinking about changing over to 64 bit, but I was just curious about whether or not I'll have to worry about incompatibility with a few 32bit-only applications I use, once I've set up multilib. I'll test it out in vbox when I get home but I wanted to check here to see if I could maybe get a solid yes/no/maybe answer.

I recently decided to install Ubuntu 11.04 on a 320gb hitachi sata hard drive. This is going into a new system with an Asus MB, AMD Proc, not sure if this matters. Anyway I can not set the bios to use ahci and see the sata drive. I can only use IDE mode with sata enabled. Asus support says to install ahci for os. If I boot into the USB install key and attempt to the install OS I receive a read/write error. I have another drive on IDE that has 11.04 on it and if I try to format the new drive and partition it with Disk Utility it fails with "Error formatting drive: error creating partition table: helper exited with exit code 1: error calling fsync(2) on /dev/sdb: Input/output error". I have tried to use dd and fdisk but I don't believe I need these until I do something else first just not sure how or where to look.

/sbin/udevd --daemon eats about 10-15% of cpu which is quite high. I found out that it is caused by AHCI. If I turn it off in bios, udev takes only about 0-1% of cpu (which I consider normal). However turning AHCI off is deadly for Windows Vista (I have dual boot) - it always ends up with BSOD. Actually, I don't even know what AHCI does. Of course I found some information on the net but I didn't found whether there are some advantages for me. Is it worth 10-15% of cpu (consequently shorter battery life)? On the other hand, I have no interest in changing my bios settings every time I boot to Windows so it would be much confortable to have it turned on all the time. The best solution would be to find out why AHCI does this and how to configure udev to avoid it. And I don't know how.I have OpenSuse 11.2, kernel 2.6.31.12

Here is my problem: In short, it takes forever (6 min), and lots of prodding to get Ubuntu to boot. Im running a Toshiba NB305 netbook (Bios 1.40), set up for dual boot with 10.04 UNR. Windows partitions boot fine. Can boot 10.04 from USB stick.
Here how I try to boot: From grub menu select "Ubuntu, with Linux 2.6.32-22-generic" If it doesn't work, I run the recovery version, and then run the regular one again. Somehow that resets stuff.

If I change my sata mode from IDE to AHCI grub won't show (cursor goes to top left) when I power on my system. After that, I press the reset button and my grub shows ok.
So, to use AHCI I always have to use the reset switch button.

How can I force my kernel to use the ahci driver when both the ahci & sata_nv are built into the kernel.?
My MSI board bios doesn't have an option for "AHCI MODE". The only sata option that it has is "called "On Chip Sata" & is located under "Integrated Peripherals. Also, the only values available for "On Chip Sata" are enabled or disabled. If I choose the disabled option, the sata drives arn't found & bootup fails.
I tried to tell the kernel to use the ahci driver by appending kernel options to my Grub2 bootloader but they all failed.
(eg.) ahci, scsi=ahci, ata=ahci, ahci.=0 sd=ahci
sata_nv=no, sata_nv=0, sata_nv=none
The only thing I can think of that is left to do is to re-build my kernel with CONFIG_SATA_NV as a loadable module & CONFIG_AHCI as a build-in driver. With only the ahci driver available at boot, the kernel will have to use it or fail to boot.
One more thing I want to say is that my other computer with the ASUS motherboard uses the ahci driver & I have both the sata_via & the ahci drivers built into the kernel. However, it has a bios option for AHCI MODE.
(eg.) Southbridge VT8251
Serial ATA IDE Controller <AHCI>

I have an old laptop (asus M6 ca. 6 year old) with dual boot linux windows. Untill Saturday linux=suse 11.0, Saturday I have made an upgrade to opensuse11.4.
I have boot up/down many times almot everything was working properly except the battery status ... I have thought .. "I'll think about it later".
Then out of the blue on sunday my laptop does not boot anymore, the boot hangs. I then have realized taht the failsafe boot was working properly.... ok I have remembered the wrong battery signal and tried the normal boot + acpi=off .. and .. it boots!
OK, the acpi is the problem. I have never made an update of my BIOS (this means it is now old), but I do not really want to update it now. with suse 11.0 the acpi was working properly, I have never have touched the acpi boot option and I had all acpi functionality working (battery, suspend .. etc)
how to let acpi work (at least for the main features .. batetry, fan speed, HT ... etc)?
It can be that the old kernel boot was using some "specific flags", (an installation is cleverer than an upgrade ..?!?!) but unfortunatelly it looks to me that nothing has remained from the old installation .. so I do not know ...

I have an ubuntu 10.04 system. I have been trying to install tcl with non-thread enabled for some other software. If I install tcl from synatptic or use activetcl, then it gets installed with thread enabled option.
So I thought that I have to compile tcl from source. So i downloaded tcl8.5.8-src.tar.gz file of tcl and extracted it in a folder.I then entered the /unix folder and i ran ./configure --disable-threads and got this output:
I then did sudo make and got:
make: *** No rule to make target `/../unix/Makefile.in', needed by `Makefile'. Stop.

One of my 2 harddisks, a Hitachi HDS72101, is very slow, the driver is ahci.
Output of "hdparm -t /dev/sda":
/dev/sda:
Timing buffered disk reads: 8 MB in 3.20 seconds = 2.50 MB/sec
No problem with the other one, a Hitachi HDS72161, the driver is pata_ali.
Output of "hdparm -t /dev/sdb":
/dev/sdb:
Timing buffered disk reads: 224 MB in 3.00 seconds = 74.63 MB/sec
How could I get better performance for /dev/sda ?

In order for TRIM to work on an SSD with encryption, I need to make sure to "select the AHCI option before installing the operating system."Does anybody know how to do this? I have no idea what this is talking about. I'll be installing 11.04 with no dual-boot. Just Ubuntu alone.

I have a HP Pavilion dv7-2230sa During boot I get a series of errors about ACPI and AHCI Conflicts, the result of which I have to dissable ACPI with acpi=off. However when acpi=off my wireless Broadcom b43 series refuses to enable the wifi. I just can't press the button that would enable / dissable the wifi.
The wifi is detected, the drivers and firmware are installed, however the light remains firmly in the RED.the ethernet works, sound works fine, There also seems to be an issue with the ATi/Radeon Driver being missing which is causing fatal errors at boot time and also some memory conflicts again causing fatal errors.
I have tried this laptop under opensuse 11.2 and now under opensuse 11.3M5 without sucsess - however to my dislike Ubuntu have managed to resolve this by accident between 9.4 and 9.10 but i wanna use opensuse not ubuntu i have asked them to tell me how they fixed it to share it with you but I am still plowing my way through their forum!

I am about to do a clean install of 10.04 (64-bit) on a ThinkPad X201. The machine will only be running Ubuntu (i.e., no dual-boot). Is there any reason to use compatibility mode for the SATA boot drive, or will AHCI work fine?

I want to run my Debian install in AHCI mode on my computer. It runs perfectly fine, all drivers etc work perfectly also. The computer itself is in RAID mode but with all 4 RAID channels disabled (I refuse to use any RAID arrays because I simply don't like them). However, my computer (Acer Aspire m3640/m5640, motherboard MCP73PV/630i) has greyed out the option for me to change the option from RAID mode to either IDE or AHCI. Since I do not use RAID at all, I want to change to AHCI but it is greyed out in the BIOS. This option wasn't greyed out before as far as I remember.
I also have Vista x64 installed on a SATA drive along with Debian all partitioned. I also have an empty IDE drive attached which will be used for another operating system AFTER I have changed to AHCI mode. The SATA drive has the boot flag. I use GRUB to boot the operating system. My BIOS version from American Megatrends is R01-A3 (not the latest one, but the one I need to use). My question is this, how could one possibly go about as to changing it to AHCI mode from RAID with the BIOS greying the option out. how to make the BIOS ungrey the option (if there is another option preventing it from being changed or if the harddrives need configuring etc). I am not particularly concerned if the drives need to be wiped.

I realized after spending some time performance tuning my mini Linux server that the hard drive is stuck in IDE mode, and I can't get the controller to be discovered in AHCI mode.EDIT: I should add that I'm running Vector Linux 6.0 Lite, which is based on Slackware 13.0. The Kernel version is 2.6.27.12.
The mobo in question is actually a small mini-ITX board from Foxconn. Here is a links to the specs:url.I use it for a media server, and so far the drive I'm using (Hitachi HDE721010SLA330) is working fine in IDE mode (apparently).
I have a strong suspicion that the crappy Foxconn BIOS supplied with the board is not initializing the Intel 945GC controller in AHCI mode. There is a BIOS entry for setting the controller to "Advanced", but I don't think it's doing the job.
Here is an "lspci -vvnn" of my system:
Code:
00:00.0 Host bridge [0600]: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub [8086:2770] (rev 02)
Subsystem: Foxconn International, Inc. Unknown device [105b:0d4d]
Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort+ >SERR- <PERR- INTx-
Latency: 0
code....
Is there anything I can do to get the drive/controller in ahci mode, or is the BIOS screwing me?

I am using Centos 5.4 on an Intel DG451D Main Board. Two SATA drives in RAID1 mode via the main board's built in AHCI controller. It seems to work just fine but I would like to be able to monitor the state of my drives and controller, especially during a re-build and make configuration changes etc if possible, so new drives can be added etc from within the OS. Is there a way to do this within Centos or am I stuck with using just the BIOS configuration system? Apologies if this is a stupid question - I am pretty new to this and have spent several hours trying to find a solution to my question but to no avail.

Server has DQ35JO board, 8GB memory, multiple SATA hard drives. It was happily running Fedora 10, and Fedora 9 before that. I downloaded and burned the F11 DVD, booted it, did an install which is:
-- delete the LVMs
-- create a 200 MB /boot on ext3, the rest of /dev/sda on ext3 as /
-- reformat the swap partition on /dev/sdb1
-- leave the other file systems alone (they are all ext3)
I chose no optional packages and let it install. It finished normally and got to the "click to reboot" screen. Now, my server is completely bricked. When I power it up I get a blank screen with a blinking cursor. I cannot even get to the BIOS, or boot my Fedora DVD, much less boot the boot drive.
