Software RAID broken on Alpha
Hi
I have a here a Alphaserver 1000 with some SCSI discs. I run 2 of them as
RAID 1. I get this error on every boot. I have now kernel 2.4.23, but it
also happend on a .22
The kernel detects the drives correct:
Attached scsi disk sdb at scsi0, channel 0, id 1, lun 0
Attached scsi disk sdc at scsi0, channel 0, id 2, lun 0
and loads the md drivers without problems:
md: raid1 personality registered as nr 3
md: raid5 personality registered as nr 4
raid5: measuring checksumming speed
8regs : 376.832 MB/sec
32regs : 598.016 MB/sec
alpha : 688.128 MB/sec
alpha prefetch: 598.016 MB/sec
raid5: using function: alpha (688.128 MB/sec)
md: md driver 0.90.0 MAX_MD_DEVS=256, MD_SB_DISKS=27

But when the driver should setup the raid, strange things happen

I don't know who this came (a guy from SuSE told me, that they tested the
md-code thorughly on many plattforms but he doesn't know exactly, if alpha
was among these).
It could be a broken hard drive, but I don't think so.
