sometimes it is much more profound than this. it just look like
complete garbage has been dumped into the file.
i failed to mention in my first message (i should fall out of the
habit of making posts when i am on the verge of unconsciousness), that
there is a strong possiblity that there is a SCSI factor to all of
this:
**Tagged Queuing** **Kernel Version** ** Corruption **
off 1.2.13 never
off 1.3.77 never
on 1.2.13 never
on 1.3.77 always
this seems to imply that it isn't a hardware problem. it does however
seem to point a finger at the SCSI code. however, it could be some
bug which is brought out by the (much) increased disk performance when
tagged queuing is turned on.

well, here's the breakdown on my system just in case it is of any use
to anybody:
P166 (brand new)
32MB EDO RAM
256k pipelined cache
Micronics M54Hi Motherboard
PCI 3c590 ethernet (vortex)
PCI Buslogic BT-948
PCI Triton IDE
PCI Diamond Stealth Video VRAM
ISA Soundblaster 16
Conner CFP2107S SCSI drive
i don't have this problem on any of the (slower) linux boxes that i
take care of. unforunately, none of them are PCI so i can't try the
buslogic card in one of them.
