Fedora :: Default 32 Bit Kernel Support More Than 4GB?
Feb 18, 2010
I just want to know what is the default Fedora 32 bit kernel - does it support more than 4G memory. I would like to save myself from compiling custom kernel and all following fiddling (nvidia drivers, virtualisation software etc) and 64bit OS is not for me - too many apps that I need are missing, of poor quality or need more manual intervention. Actually if bigmem / whatever it is called is configured in the default kernel, this may be the reason to switch. I intend to use 4 to 8 GB memory and it's a desktop, so server builds (like Ubuntu) are not for my taste.

I am installing a new large 4 Tb RAID (hardware) under 9.10. Does GPT support come by default in the new 9.10 kernel? How can I check? I gather I need to use PARTED to make a GPT partition table on the raid. Anyone know details of how to do this? [URL]...

I've a PowerMac G4 MDD that has OS X Leopard on it. I have repartitioned it to accommodate an Ubuntu install. However, I have no Disk Drive in the G4, it was broken so I removed it. Now I have an iBook G4 I have tried using an ubuntu cd on to install to the said PMac in TDM, but of course after reading the Ubuntu kernel doesn't support install to firewire by default. Can someone help me by compiling a Cd image I can use to accomplish this or tell me how without the use of another linux box?

I'm trying to find out when QME2572 (Qlogic) card became support by the kernel. We have a RHEL 5.1 system that is moving to new hardware, however the kernel at this release doesn't support the new hardware, due to the Qlogic card change. I tired the Redhat KB and Bugzilla. Is there a Kernel change list etc I can search. Never really played around with the kernel too much so I'm just after some pointers for looking up this information. Offically its not supported until Redhat 5.3, I'm trying trying to research kernel info so I can tell the customer they have to upgrade.

I've just downloaded F11 i386 installation DVD. I installed it on my laptop and just now noticed that PAE kernel got installed. Isn't PAE for systems with RAM >3.2 GB? It's a pretty old laptop (P3, 256MB ram). So, is PAE kernel ok for me or should I reinstall from scratch and use some specific switches in the installer to get non-PAE kernel? I've also read that Yum doesn't recognize PAE packages dependencies and will install non-PAE kernel modules if I try to install let's say Nvidia driver or so.

Lately when Fedora 12 updates the kernel it defaults to the last kernel entry and not the newest one. However I set grub to boot entry 0 as the default which is allways the new kernel. It runs like this fine until the kernel updates then it seems to change from 0 to 1 on its own is this a new planned aspect of the new kernel being installed?

I have a sata card in my RHEL5 server that is not working. It has a 1.5tb hard drive attached to it that I would like to use. It seems that the 2.6.18 kernel did not detect and use it by default. I was able to find some info about the

differences between Kernel Default and Kernel Desktop? I've found some past threads like this link and this other link, and some other google info, which suggest the only difference would be the io scheduler. Also, I see the default grub choice is "Desktop" and not "Default", so I take this as a suggestion to prefer one over the other.
However, my broadcom 4312 wireless only works on the "default" and not on the "desktop" kernel, so I guess there must be other differences. I just want to evaluate which one is the less long-term risk option to go.

about 2 weeks post-install, I find that my new debian etch machine has limited support for different filesystems. In the past, I've always seen support for riesers, xfs, ntfs, fat32, of course ext2/3,. I was trying to mount and read an old windows ntfs HDD, and there were problems, so I went to:
cat /proc/filesystems (see below).
Is there any way to get back support for other filesystems on my kernel, or do I need another kernel, or do i need to compile a new kernel? Maybe just install the system over again? (if I do, how do I select for filesystem support)...

A while back I compiled a custom kernel, 2.6.35. I forgot to add UDF support when configuring and compiling. Will I need to re-compile the kernel to get UDF support or is there some other way I can add it?

I use Slackware 13.37 32-bit version on ThinkPad X60s. I compiled two Window Maker dockable applications monitoring the processor temperature, fan speed, and battery status: wmpower (see: [URL]) and wmlenovo (see: [URL]). Both these applications refuse to work.
wmpower displays the messages:
Code:
CPU frequency scaling available
No power management subsystem detected
No power management support...
wmlenovo displays the message:
Code:
No ACPI support in kernel
Did I missed something obvious during the configuration of the system and ACPI doesn't work for me or there's some more serious problem with my system?

I am a long time (1.something) slackware user and maintainer of a mirror site.I'm suddenly having problems with my favorite distro. (1) I've been mainly running Slackware64. When I was experiencing recent problems on a Slackware (32) 13.1 system, I discovered the huge-smp kernel does not support more than 4G of RAM. This is an obvious bug, and I am shocked that there is no fix out yet. Surely I can't be the only Slackware 32 user with >4G of RAM. I've verified it on a 12G i7 system and an 8G Athlon64-X2 system.

I'm experimenting with a load balancing setup and have found some pretty good guides, but they all assume that ipvs support is built into the kernel already. e.g. http://www.howtoforge.com/high_avail...apache_cluster
So of course "modprobe ip_vs_dh" simply outputs "FATAL: Module ip_vs_dh not found."

I have been unable to boot my CoreExpress Atom Z530 based board from flash, because my 2.6.31.6 kernel does not seem to have support for the (US15W chipset) IDE controller configured. I have read many web links that point to CONFIG_PATA_SCH as the key, but that does not work for me. I _can_ boot RedHat 2.6.18-164.e15 which does not have CONFIG_PATA_SCH configured, but I believe they are using initrd.

and I have done some research on the Realtek ALC892 chip and I am unsure if it will work. I am currently running Linux Mint 10.
I see that Realtek offers a driver but I have not found anybody who had success or if it was built into the Kernel.

I compiled my own kernel with tun/tap and bridge support. Both modules load fine at boot time (I could read that in the dmesg output). Now I want to use it, and the /dev/net/tun node is not there, so my application gives that error. I'm trying to bridge openvpn connections. Is it possible that udevd is not doing his work?
PS: I'm on a WD MyBook World Ed NAS device. It's ARM, so I cross compiled the kernel from my debian linux machine. I also installed debian on the NAS.)

I was wondering if there's a way for me to get real-time kernel support on regular Ubuntu 9.10 through some sort of update. I know Ubuntu Studio has a real-time kernel, but I'd prefer not to use it. I'm a fan of the original Ubuntu.

I have a PCI SCSI controller with this chipset that was working fine in 10.04 to drive a Polaroid Sprintscan 35 Plus scanner. Having just run the upgrade to 10.10, the scanner is no longer being seen. If I go into the controller BIOS the scanner is seen there, and running lspci shows the controller as
Code:
SCSI storage controller: LSI Logic / Symbios Logic 53c875 (rev 04)
Running
Code:
sudo modprobe -l | grep "sym"
shows only
Code:
kernel/drivers/scsi/pcmcia/sym53c500_cs.ko
kernel/drivers/scsi/sym53c416.ko
kernel/drivers/usb/serial/symbolserial.ko
Seems like support for the 53c8xx chipset has disappeared?

Does somebody know what about native support by kernel for Broadcom's wi-fi chipset - bcm 43225? In kernel sources 2.6.38.3 in section "staging drivers" I saw something like "Broadcom 80211n". I selected this module for compiling, but in process I got error something like wrong type of variable or something else when module was compiling.

I have just started to work with BeagleBoard and built the Linux kernel (version 2.6.30.5) and download to the board and it start. I have also connected to the board over serial to Putty terminal.
Now I want to connect to the Beagle Board using USB instead of serial and I am looking for some info on how to do this.
My goal would be to connect to board over USB and then be able to:
* Download my own binary files/programs from PC over USB to BeagleBoard
* Communicate over USB instead of UART/Putty to get log and execute commands
Question:
How do I build the Linux kernel with USB support, meaning what settings should be ticked in menuconfig? Or is it already included?
How do I enable USB OTG in menu config?
I assume I would need some driver on my PC with Windows XP to connect to my BeagleBoard over USB. Were can I find this USB driver?

I'm done following this guide about Kernel Building. [URL] .... and I got done successfully, the .config file was the very default obtained from "make menuconfig" the only extra thing added was:
Code: Select allCONFIG_USB_EHCI_HCD_ORION=y
All dependencies had to be installed about 2GBs for kernel building to function properly, mainly due to the needing of kernel headers. It loads successfully on my desktop whether or not it needs that module (if it was added correctly) but my goal was to add xhci support so it will load from my laptop, still won't load from the laptop giving me a initramfs prompt. Adding that code line to the .config file didn't seem to do what I wanted.
Although since I did a "make-kpkg clean" command as requested by the manual I dont know if it used that line or not to be honest. since I think it deleted the .config file in its efforts to clean old configs so I don't know I'm new to kernel building.
