Hi,
I've had some bug reports in the kernel output on a server that I have
been commisioning. The box is a Dual Opteron, running 2.6.5rc3 (64 bit
build), with 4 250G WD SATA drives, via libata (sata_sil driver).
I had previously seen a kernel panic on the box during file I/O whilst a
RAID5 array was being resynced - I didn't manage to get any backtrace
out of it, but had been trying to make it fall over since (by loading
disk and/or CPU during a RAID rebuild).
To force a resync, I manually removed, and then re-added /dev/sdd3 from
md4, but during the resync, there appears to have been a bad sector on
/dev/sdc3, and the rebuild stopped. I then used mdadm to stop, and
recreate md4, and afterwards, things seemed to go slightly haywire.
Here is the output of /proc/mdstat for the box now (also as it was then):
brie:/tmp/fah$ cat /proc/mdstat

I'll paste in a portion of /var/log/kern.log with [annotations]..

[ There seem to have been approx 120 of these messages per second - for
this hour, until I manually stop the array using mdadm. At this point I
try to restart the array, before giving up, and recreating it. The
resync then appeared to go OK, and I've just done a read check on
/dev/sdc with no errors, so I suppose the drive had a temporary hiccup.]
