> is it possible you are reading or writing outside the bounds of the partition?
no, the errors occured while filling venti and that partitions dont overlap. at
least disk/prep didnt complain as i created them. the offsets are more or
less random.
my dd-testscript was not that successfull in provoking errors.
in the case of the adaptec, i started 2 dd's: one reading from sdC0/data and the
other reading from sdD0/data. the last dd i started killst the first and the
first
returns i/o error with no delay.
ok... lets leave that out (we dont know if this is really related) and keep on
the via chip.
i'm now testing with IDE (no RAID) mode one with single drive (sdC0).
just tried to create some disk load so i created venti arenas and isects
and started:
vac -h 127.1 /sys &
while(){ dd -if /dev/sdC0/data -of /dev/null -bs 65536 }
it paniced and here is the dump from serial console:
