kernel module file corruption on reboot
From: Stephen Olander Waters

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=417594
Package: linux-image-2.6.18-4-amd64
Version: 2.6.18.dfsg.1-12
Please note that this bug also affects the latest Debian amd64
experimental kernel linux-image-2.6.20-1-amd64, version:
2.6.20-1~experimental.1~snapshot.8402
About every 5 reboots, my kernel module directories will get corrupted
-- if I'm very careful and shut down first, boinc running in a 32-bit
chroot and second, GDM. If I just type in "shutdown -h now" in an xterm,
it almost guarantees corruption.
The most common corrupted file is tg3.ko and its parent directories.
No other filesystems experience corruption. No other directories
experience corruption. Only the kernel module files/directories of the
running kernel are corrupted.
Annoying workaround:
1) reboot into rescue kernel
2) turn off networking / portmap
3) remount readonly
4) run fsck on root partition where the module files are stored
5) remount read/write
6) dpkg -i /home/user/saved_kernel.deb
Hardware:
Dual opteron 244s
MSI K8T Master2-FAR motherboard
via K8t8000 chipset
RAM with ECC turned off because the motherboard doesn't like x8bit ECC
and I can't afford to burn more $ on 2GB of new x4bit ECC RAM.
Here is some weirdness in dmesg with the hard drive. It has always had
this message, even when it was running on 32-bit kernels, but even then
I never experienced filesystem corruption with it.

Software:
Debian unstable + above mentioned kernels
All partitions are ext3 with internal journals mounted in data=ordered
mode and all defaults.
Thanks for any help! I appreciate all the hard work you guys put into
these kernels. If you want more information, just ask.
