The 2.6.16-git3 snapshot is stable for me like -rc6-mm1 and -rc6-mm2 are :-)
To recap: Running eight Maxtor disks connected to a MV88SX6081 8-port SATA II PCI-X Controller (rev 09)
mdadm -C -l5 -n8 /dev/md0 /dev/sda1 /dev/sdb1 /dev/sdc1 \ /dev/sdd1 /dev/sde1 /dev/sdf1 /dev/sdg1 /dev/sdh1
mke2fs -j -m1 /dev/md0 mount -o data=writeback,nobh /dev/md0 /mnt
for i in `seq 4` do dd if=/dev/zero of=bigfile.$i bs=1024k count=10000 dd if=bigfile.$i of=/dev/null bs=1024k count=10000 done time md5sum bigfile.* time rm bigfile.*
or
for i in `seq 4` do ( dd if=/dev/zero of=bigfile.$i bs=1024k count=10000 ; \ time md5sum bigfile.$i ) & done
Kernel 2.6.16-rc6 and 2.6.16 always crash during the md5sum (and leave no output).
2.6.16-rc6-mm1, 2.6.16-rc6-mm2 and 2.6.16-git3 are stable without a crash or data corruption.
I'm aware that the test is very simple and bugs might still hide. I'll go and find some more serious stress tests.
Should I do more testing/bisecting/etc?
Btw, I do still get these (any kernel), but with no visible effect:

Thanks!
