Does this mean that with normal 686 or 486 kernel the corruption doesn't
happen?
However many years ago i've experienced frequent filesystem corruption
but i couldn't figure out why. Eventually i discovered was some hdparm
settings...
Was a lot hard to find, so i hope this could help you. ;-)
for sure i can't guarantee that this isn't related to some hardware
fault like broken ram or the like but i checked ram with memtest86+.
If i were you, i would also install smartmontools and try something like:
smartctl -a /dev/yourdisk
I'd put particular attention in the "Vendor Specific SMART Attributes
with Thresholds" table to find something strange.
And try to hear if the disk make suspicious noise.
If you have a minimum suspect for the ram, try to temporarly remove some
bank, if you have more than one, or replace completely if you can. In
the past i've seen at least two cases where memtest run ok for about a
day but the system had sporadic system freeze and BSOD (Windows PCs).
When i've replaced the ram the problems disapperead.
Bye.
