i have similiar, perhaps related problems. the system is a p166
w/32mb or ram, buslogic bt-948, conner scsi drive, etc.

i can repeatedly, without fail, achieve filesystem corruption under
1.3.72-82 by unpacking two previously gunzip'd linux kernel source
trees while cat'ing eight copies of /dev/mem into seperate files
(probably don't even need to do all of that, it seems to happen by
itself just by unpacking a single source tree). running a diff over the
source trees reveals massive file damage.

no matter how hard i try, i cannot get filesystem damage to occur
under 1.2.13 (and believe me - i tried pretty hard) ...
