** Summary changed:
- Kernel lockup while rebuilding two mdadm RAID arrays
+ Hung task warnings while rebuilding two mdadm RAID arrays
** Description changed:
I have the following RAID configuration: md0 is a RAID1 array used as
the root file system, md1 is another RAID1 array used as swap.
= /proc/mdstat =
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4]
[raid10]
md1 : active raid1 sdb2[1]
3020096 blocks [2/1] [_U]
md0 : active raid1 sdb1[1]
23037056 blocks [2/1] [_U]
unused devices: <none>
- I had added the missing devices to their arrays (respectively, sda5 to
- md0 and sda6 to md1), triggering a spare rebuild for both arrays, and,
- some minutes later, the system froze. The relevant section of
- /var/log/messages is attached: unfortunately, the kernel dump is not
- complete.

unfortunately, the kernel dump is not complete.
+ Update: the system did not freeze when the problem was reproduced a second
time; therefore, just report the warnings about the hung task.
Using Intrepid Ibex Alpha4 + updates, linux kernel 2.6.26-5-generic
