Hi Rui,
Is that a RAID1 ou RAID5?
It's a RAID5, but the problem also happends on RAID1.
Can you give the output of these commands?
mdadm --misc -D /dev/md3
mdadm --misc -E /dev/hda4
mdadm --misc -E /dev/hdb4
mdadm --misc -E /dev/hde4
mdadm --misc -E

Remove the

line from mdadm.conf (it is wrong and un-needed).
Then

Thanks - that patch applies OK to more recent 2.4 kernels and appears to
