Hi Andrew,
I am having fsx failures on 2.6.19-rc1.
I don't have any useful information at this time to track it down.
I am running 4 copies of fsx (+ fsstress) on a 1k filesystem and
one copy of fsx dies.
FYI.
Thanks,
Badari

Hmm, so fsx-linux wrote something and read back zeros. Strange. Do you
know what that 'segfault' message means? I cannot find it in my copy of
fsx-linux...

Random. It happens any where from 1 hours to 6 hours.

fsx got a segmentation fault and died. These are the messages in the
dmesg.

I've never seen fsx die that way before... can you get a coredump to see
where it was at?
