Kernel Panic in 64bit Arch Linux after Kernel Recompile: 2.6.35-rc3


Hello,

I have recompiled a few kernels, but all on 32bit systems so not sure if that has anything to do with it.

Running Arch Linux 64bit, most recent version.

Kernel Output:
Code:
kjournald starting. Commit interval 5 seconds
EXT3-fs (sda6): mounted filesystem with writeback data mode
VFS: Mounted root (ext3 filesystem) read only on device 8:6
Freeing unused kernel memory: 764K freed
Write protecting he kernel read-only data: 10240k
Freeing unused kernel memory: 764k freed
Freeing unused kernel memory: 1580k freed
INIT: version 2.86 booting
init[1]: segfault at ffffffff81008821 ip ffffffff81008821 sp 00007fff59c630e8 error 15
init[1]: segfault at ffffffff81008821 ip ffffffff81008821 sp 00007fff59c630e8 error 15
init used greatest stack depth: 3792 bytes left
Kernel panic - not syncing: Attempted to kill init!
My first thoughts was that it might be my grub bootloader configuration, so had a big play around with that but it didn't fix it. Also made sure support was built for filesystems. However almost all that Fstab mounts are ext3 anyway, and certainly the root and /boot are.
Now thinking it may be a memory error so will run a check when I shutdown.

Thanks very much!

Since you are using an rc3 kernel, I would suspect a kernel bug. Grub is doing its job as it finds vmlinuz/initrd and loads them. It's crashing after the kernel loads and while attempting to run /sbin/init. Have you tried the most recent stable kernel?

Cheers, have only tried the stable on 32bit as this 64bit is a fresh install. Though did manage to recompile the rc3 on 32bit Arch. Will give it a go and keep you posted. The memory test went fine, no errors.

Hmmm, just tried the most recent stable kernel and I got pretty much exactly the same error.

I did a memory test and everything seemed fine, and I have tried building support for more filesystems. I'm fairly sure the confgiuration would not result in a panic for a 32bit. Does anyone have any ideas?

Thanks
