Per your instructions .... I tail -f'd /var/log/dmesg and /var/l0g/messages,
and then executed the four mdadm commands below, for the faulty array.
After removing and re-adding the faulty disk partition to the array, the
array
returns to faulty state almost immediately. During the process, dmesg
didn't
show anything, but the information written to /var/log/messages is at the
bottom hereto.
I suppose one answer is that there's a hardware issue with the array, or
one of the disks. But that would be surprising to me - both the hardware
array and the disks are new, and the setup (hardware/software/RAID) worked
fine until I tried to upgrade my kernel. Possibly RAID-related formats are
different between kernel 2.6.28 and 2.6.31????
Anyway, would appreciate diagnosis/recommendations ...

Can you attach full output of 'dmesg' after raid degradation?
For context, there are four RAID devices on this system. md0 is
/boot, md1 is / and md2 and md3 are the problem devices. /proc/mdstat
is below followed by the output of dmesg.
/proc/mdstat

dmesg .....
The dmesg doesn't contain ATA error messages and the actual
degradation. Can you please trigger that and then attach dmesg?
Thanks.
