Ubuntu :: Acpi=off Required To Boot, But Won't Shut Down?
Feb 17, 2010
I've built several computers and installed Ubuntu on each one, and I've never had problems until my latest build. Here are the problems:The computer requires acpi=off to boot, and it won't boot with acpi=ht. I've searched for this, and there's a widely reproduced acpi troubleshooting guide that says that this means that there's something wrong with the acpi tables themselves, but I haven't found any fixes.If I go ahead and use acpi=off, then the computer works fine, but it hangs on shutdown. I've searched for this too, and the consensus seems to be to remove acpi=off from the boot options. This, of course, is not an option for me.
When I run OpenSUSE from the Live CD using normal settings, booting stops with a blank screen a moment after the kernel is loaded. When running it with ACPI disabled, it works, but direct rendering is disabled, even though it detects my video card (Mobility Radeon HD 5650) correctly Here's the Xorg.0.log file: my xorg log - [URL]
Having trouble rebooting a system. Have a Ubuntu 9.10 (2.6.31-16 generic-pae) build on a VMWare installation. The system was fine until I rebooted after an update. Now I get the above message and the system halts loading. Have tried to Grub acpi=off and acpi=force to no avail.
I haven't been able to use linux for like 6 months I've tried Fedora 14, Debian Testing, Ubuntu 10.04 and now Mint KDE.
Whenever I boot any distro my laptop acts randombly, it gets to GDM and it freezes, or it lets me login and then freezes or works really slow, even through the shell.
The only thing I could figured is to insert acpi=off on the boot commands googling around, and there it boots.
My problem is that it gets overheated, I can't use any porcessor policy and I can't suspend my laptop with that boot line.
I have random X freezes (suddenly keyboard and mouse stop to react). Xorg.O.log is error and warnings free. The only problems I see in syslog/ dmesg are related to ACPI.
I have Asus P5E3 Deluxe motherboard. Slackware 13.1

I ahve also today upgraded my BIOS to 1303 version. Still no difference.
My openSuse install can't boot/login with ACPI enabled. I disabled ACPI and have been using it for a while, but would like to get ACPI working.
When I did the install from the livecd it would hang when loading the kernel. I would see the progress indicator get to 99% and then my computer froze. I disabled ACPI from the options and was able to install.
But I never got any error messages or any other output so I don't know what module was causing the problem when being loaded.
I recently put together a new machine with Ubuntu 9.10 I couldn't boot it even live (or any live distro for that). It wound up being either a ACPI or APM setting in the BIOS that got it to boot, I say either because I spent probably 10 hours in there turning things on and off until it worked. It was about 4am so my memory of it ain't that great. TO get up to date, I was adding a HDD and having some issues with it being detected right. So back in the BIOS I was and accidentally loaded the defaults! Now I can't figure out what I did last time I've been at it for hours with no luck.
If I jump into grub b4 it boots and add the acpi=off the system boots up but with the side effects of no pwr mgmt. I need it to be able to sleep and shut itself off. I've always had good luck with Ubuntu in other machines so I'm not that great in there, and honestly don't know the difference between apm/acpi. The MOBO is an ASUS P4C800 Deluxe, AMI Bios. I'm gunna keep at it in the mean time, if by any chance I figure it out I'll post what it was (after I write it down).
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 ...
It's only been a couple of days since I formatted my toshiba laptop's hard drive (i was running fedora without significant problems) and installed slackware 13.1 32bit. I did a network install because the dvd drive is not functioning properly. everything installed fine with the hugesmp kernel, but I started not being able to boot the laptop every single time I wanted to (especially after a reboot but also after a power up).
my observations:
-the pc might freeze in the very first toshiba logo screen (where you are prompted to press F2 to enter BIOS)
-or it might freeze when I get the lilo boot loader (not even the count down to choose kernel starts) - but i CAN use the arrows and press 'enter' to choose to load a kernel manually
-or just after it loads the kernel and the bios checks
-or during boot after in loads ACPI thermal zone
-or a little later during boot when the dhcpcd if broadcasting for a dhcp lease.
the first 3 are freezes, the last 2 are resets. especially if i need to reboot (or get the resets of the 2 last case), I will surely get stack in one of the first 3 cases afterwards! i have observed that rarely, after such a reset, if it actually gets stack in the toshiba logo, i might be able - pressing the poiwer buttonj repeatedly to actually overcome the 'freezing' there at which time i'll get to the lilo loader (the count down timer will not.. count down), but i can press 'enter' and I will finally get stack after loading the kernel and bios checks
So I have to powerdown the laptop and start all over again. Sometimes the whole boot process will proceed smoothly. and i'll get to a login prompt, and when I do I can keep the laptop up and running for virtually ever. that is it doesn't seem to be slackware related... Hwever the problems started after I installed slackware. I didn't have any problem with the fedora installation and i wonder if it has something to do with the network boot.... additional note, with feodra i didn't have a problem restarting or shutting down the laptop. now if i restart, the pc will go through the process of shutting down, but it will never actually reboot - i'll have to do it manually..
I just installed Fedora 12. When I boot, only the following three lines are printed: pnp 00:09: can't evaluate _CRS: 12298 ACPI: Expecting a [Reference] package element, found type 0 Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) I first installed Fedora using a RAID 1 setup that mirrored each partition, so I thought the problem was coming from GRUB and confusion from what to boot off of. However, I reinstalled Fedora using a simple single drive setup (left the second drive without any partition), and the same error was returned. Is this an ACPI issue with this particular motherboard/BIOS? Any ideas for how I can fix this?
Offlate I installed F11 i586 on my laptop. F11 shares the hard disk with Vista Home Premium 32-bit. The problem is that when running F11 (or even Ubuntu), my system shut off suddenly(not a normal OS shut down, but a sudden power off without any warning). This could have been a hardware trouble(heating) but it doesn't happen with Vista. Machine specifications: Maker: Toshiba Model: Satellite L305D-S5881 AMD Turion X2 Dual Core Mobile Processor RM-70 3072 MB 800 MHz SDRAM I don't want to open up my machine unnecessarily, if it isn't a hardware issue. I am not sure how to verify the bit length of the machine and the OS and does it create a compatibility issue ? Your advise would be highly appreciated.
I've just renamed my Mythbuntu 9.04 machine which was running a frontend and master backend. It's now a frontend and slave backend with a different machine name. All is working in that the connection between slave and master backend functions without problems. However, the mythbackend on the slave will not start on boot - I have to start it manually from the terminal. In addition, the power button on the machine will not shutdown the machine any more - I can only shut it down from the terminal.
I've installed Ubuntu 9.10 approx 1 week ago and it's been fine. Last night, Ubuntu froze while I was running several programs. I wasn't sure how to pull up any type of 'task manager' and the mouse didn't move so after several minutes I was forced to hard reboot the computer. Grub starts and allows me to select Ubuntu but won't get past the log-in screen (allows me to log-in but freezes immediately after hitting enter). I started the recovery mode and the errors show what I believe to be sector errors (?)Do I need to run a 'chkdsk' from Windows or re-install Ubuntu? If deleting/un-installing Ubuntu (through Wubi) is necessary, is this a problem directly related to Wubi (i.e. is a clean install on a seperate partition better than installing through Wubi)?
I have Fedora (12 plus some rawhide, but mostly 12 because I am not up to date) with the Nouveau driver. I tried to switch to the solar plymouth theme, but I only see the ASCII progress bar at boot. But when I shut down, it work nicely. (I have updated to initrd and menu.lst)
After installing 11.04, I have enabled the Nvidia proprietary drivers and I see this (picture of problem is attached) at startup and shutdown. About nine out of 10 times, I cannot get to the log in screen (even in recovery mode); however, on the tenth try, everything works properly and I can even play games, ex. Braid and World of Goo. I get about 3700 fps running glxgears.
I have run nvidia-settings and dpkg and various other things in an attempt to get it sorted out. Additional Drivers says that the "driver is activated but not currently in use." I'm not sure why that is.
I have a Ubuntu - windows 7 dual boot (in two partitions of the same HDD) desktop PC for a few months. I was learning terminal commands and, although I don't think I made such a big mistake, but the fact is that the a very strange thing happenned: "Preferences" and "Administration" from System disappeared as it did also "Applications". After rebooting the same it remained the same. No big deal, I thought, because I haven't yet saved any important work on Ubuntu. So I reinstalled Ubuntu. Done that everything was nice until I booted Windows... Since then I counldn't start windows after GRUB due to:
Status: 0xc000000f Info: The boot selection failed because a required device is inaccessible."
Windows Live DVD Repair is useless. I've tried CHKDSK utilities, no result. Windows partition in Ubuntu's Disk Utility is OK but I can't access the files (all "broken links"), just can explore a few directories after which I find myself entering the same folder endlessly. I wanted to repair windows boot or at least recover some important files in Documents and I thought I had backup (but turns out that, for some reason that I'm still trying to understand, they aren't...).
I'm using opensuse 11.2 and a week or so ago it suddenly stopped shutting down the computer, or rebooting. It shuts the screen down and that seems to be it, so I have ti switch it off. However a day or so later it began to reboot when asked, but still won't shut down. I'm dual booting it with Unbuntu 9.04 using grub2, but it's been that way for many months without problems.
I installed Debian 5.03 Lenny successfully on my machine. I got this error during boot: ACPI : invalid PBLK length [5]. After that the Operating System boots properly and starts normally. What does this error statement mean? Is it safe to work with this installation despite this error?
I have Windows XP on one drive "C" drive, Windows 7 on another "E" drive and want to install Ubuntu on another drive "G" drive. How do I when installing Ubuntu select the "G" drive to install to?
Then how to select the operating system required from a cold boot?
I recently switched from fedora 14 to 15. Today my computer suddenly shut down during an update, as I thought it overheated I decided to clean the cooling system and reapply thermal paste. However, now the system won't boot anymore ("kernel panic - not syncing : VFS: unable to mount root FS on unknown-block").
I would like to either solve this booting problem, or mount the fedora 15 filesystem and recover some files. Whichever is easier.
I have another drive with fedora 14 (antec below) which boots fine:
I just burned the iso of openSUSe 11.4 onto a dvd, and I make it through all of the installation. At the end it reboots the computer and starts in the kernel/command line or whatever you call it. I think it's kernel. Anyway, it asks for my username and password and then it says like "have fun.." () or something and then just has like my directory or whatever waiting for commands. Is there some command to start up the OS?
When do you know when to re-boot your server? I have Centos 5.6 As my remote web server running Direct Admin. I have also Centos 5.6 as a local back up server. With a KDE user interface so i can learn the graphical and command line. How ever when i query Yum for updates locally, i can see a nice extra icon next to the updates in KDE saying will require a reboot. But on my remote web server, how would i know if a Reboot would be required?
I use Ubuntu live and wanted to run the session with ACPI turned off So at boot-time using F6 I selected ACPI=off However, pstree -p shows, on line 2,: acpid(1817) So how do i really turn ACPI off?
I have to use acpi=off because my PC is crushing/freezing during installation and 2 mins after boot up. Currently I'm using acpi=ht to enable second CPU.
The problem is that my Intel graphic card is slow and Xorg is taking a lot of CPU. I'm also not able to enable compiz when disabling acpi. The biggest problem is the MythTV that is so slow in the menu area alone that I'm not watching any TV in it lately.
When I'm not, it's crushing, no CPU spikes, no strange behavior just crushing without any logs.
I installed Powertop after reading a number of threads of threads about power consumption issues in Lucid. Though it would be good to know what I was doing. But when I run Powertop it tells me "now ACPI power usage estimate available".
