2.6.11-rc5: Promise SATA150 TX4 failure

[Joerg Sommrey]

Hi all,

a problem that was introduced between 2.6.10-ac9 and 2.6.10-ac11 made
it's way into 2.6.11-rc5.  While taking a backup onto a SCSI-streamer one
of my RAID1-arrays gets corrupted.  Afterwards the system hangs and
isn't even bootable.  Need to raidhotadd the failed partition in single
user mode to get the box working again. Error messages:

etc. until hard reboot.

The failing array consists of two partitions of two SATA disks connected
to a Promise SATA150 TX4 controller.
