Maybe I should have used "resync stalls" in the subject.

Any hints about this?  What kind of things might cause it to stall?

On occasions that my raid5 array needs to resync (power outage, etc), the resync stops progressing early on. This is on Debian Lenny. I've tried the stock 2.6.26 kernel as well as the 2.6.29 kernel from Sid.

On boot:

[ 10.022020] md: md2: raid array is not clean -- starting background reconstruction
[   10.032896] raid5: allocated 3226kB for md2

[   10.033685]  md2: unknown partition table
[   20.492246] md: resync of RAID array md2


~$ cat /proc/mdstat

md2 : active raid5 sda3[0] sdf3[2] sdc3[1]

I it resyncs find when using a live cd. Any ideas what's causing it to hang.
