I applied the patch and rebuilt the kernel. But when should this be printed=
?
At shutdown or boot? I can=B4t see it at all.
When panic occurs I got the attached text as output on my serial console.
The raidcontroller has two ata disks attached. Using RAID 1. My OS is on a
separate disk using the motherboards ata connector.
Should I disable(unplug the disks) and add a spare harddrive in non-raid
state to the raid card?
