We are currently running a 900MHz Athlon at 900MHz with a VIA chipset
mainboard. We have been experiencing strange problems and a number of
kernel panics. The debugged oopes from three of these are included at the
end of this message.
My first question is whether this could be related to the VIA disk
corruption bug which has been much talked about. Does this also affect
2.2.x or is it strictly a 2.4.x problem at this stage?
Please CC me replies since the kernel list archive I watch has a habbit of
missing some posts.
It should also be noted that every now and then I've seen ext2fs filesystem
errors on the console. badblocks does not report anything as bad.
On to the oopes. First a bit of machine info:
