Bug Description
After installing 11.04 and trying to resume from standby (suspend to ram), RAID1 seems to fail, showing the following error message:
md/raid1:md1: Disk failure on sda5, disabling device.
md/raid1:md1: Operation continuing on 1 devices.
md/raid1:md2: Disk failure on sda6, disabling device.
md/raud1:md2: Operation continuing on 1 devices.
journal commit I/O error
The error is reproducible. I tried it a second time after recreating the array and doing a fresh install. The system works fine until i suspend to ram and try to resume. The system wakes up, but RAID is broken afterwards.
Setup:
Encrypted root and home and RAID1:
/dev/md0 (/dev/sda3 + /dev/sdb3): /boot
/dev/md1 (/dev/sda5 + /dev/sdb5): /dev/mapper/root -> /
/dev/md2 (/dev/sda6+ /dev/sdb6): /dev/mapper/home -> /home

After a reboot using the Live-CD md2 is rebuilding and md1 is not detected. Trying to assemble md1 manually fails with:
mdadm: no recogniseable superblock on /dev/sdb5
