No BIOS utility here to scrub the metadata.
I reported one of the duplicates of this bug months ago and I see it
still isn't fixed. I couldn't install Ubuntu on my PC using software
RAID as I have old dmraid metadata on the devices. I've now checked up
and learned what the comments above mean and
I'm going to have to say that this is not a bug, but rather an invalid
hardware configuration. A disk can not be part of a fake raid and an
mdraid at the same time. Simply disabling the raid support in the bios
has no effect on Linux as it has no way of telling whether or not the

Peter, if you have no fakeraids you can simply uninstall the dmraid
package.

Tormod, thanks; that sort of hit me like a brick wall! I run
Linux/software raid! Wow.
I'll see what happens!
Many thanks!

Having just upgraded from 8.10 to 9.04 and experiencing similar problems
I guess upgrading to 9.10 is not a fix and the cause is the same?
On boot I get atax: softreset failed (device not ready). It then
continues booting but drops out at the file system check; the root
partition which sits on a
Thank-you. Same problem here with a 9.04 upgrade to 9.10 and dm-raid
taking the devices before mdadm. I couldn't figure out why I had no
partitions in /proc/partitions (i.e. /dev/sda existed, but /dev/sda1 was
missing) and using fdisk to rewrite the partition table created the
nodes, but mdadm

My mdadm-managed raid wouldn't mount after upgrading from jaunty to
karmic. It seems this problem is caused by dmraid trying to take over
the array. According to the Debian bug linked by Spider above this is
caused by dmraid recognising the device nodes as part of a fakeraid
array rather than as
Thanks for your report. There is a number of issues in the original
description, I will leave this report for the dmraid activation-by-
default issue. Please open separate bug reports for the other issues.

The problem here is that dmraid finds valid fakeraid signatures on your
disks, which is the only way for it to know if you have a fakeraid or
not. It would not happen if you removed the fakeraid in your BIOS setup.
A workaround is to boot with the nodmraid boot option. This, and the
fact that
