I think I figured this out.

Read the section regarding the sync_action file.

do as root; ³echo idle > /sys/block/md2/md/sync_action²



After issuing the idle command, my array says;

user@host# cat /proc/mdstat
Personalities : [raid1] [raid6] [raid5] [raid4]
     
md2 : active raid5 sdd5[0] sdg5[4] sdh5[3] sdf5[2] sde5[1]

Well done :-)

Yes, you've found the bug that was fixed by commit

which is in 2.6.25.
I'm glad you found the workaround.
