Public bug reported:
I have an amd64 machine with Edgy. There are filve disks in. One ATA
(hda) and four SATA (sda, sdb, sdc, sdd). All the four SATA disks are
composed into an RAID5 array.
The suspend part seems to be good. But the resume have problem. There is
the log from resume. I have an idea but no time for test it. So when I
makes my computer to suspend to disk the RAID array does not syncing
before power off. When the computer starting again the md detects the
raid array dirty and going to reconstructing it. AFTER the raid started
the initrd detects the suspend signature on swap device and wants to
stop tasks. It can't stop the md_resync and aborts resume and going over
normal startup.
