Hello,

with kernel 2.6.22.10 checking a raid1 or rebuilding ist does not work on one 
of our machines. After a short time the rebuild/check does not make progress 
any more . Processes which then access the filesystems on those raids are 
blocked.

Nothing gets logged. Access to other filesystems works fine.

If we boot 2.6.17.10 (the kernel we used befor upgrading to 2.6.22) the raids 
the check/rebuild is done without any problems.

The filesystems on the raid are exported via nfs.

The machine has 2 xeons with hyperthreading.

Regards,
