Do you think the latest version at
http://git.neil.brown.name/?p=mdadm.git;a=summary is stable enough to
use?   It definitely fixes the major issue (losing the raid config)
from the prior version.

It should be OK.  I'll probably make a 3.3.3 in a little while to make it
official.

Thanks.

1) The update did fix the broken RAID.  I can reboot and the RAID
mirror still exists after reboots.

2) I do want to report that on the first test, the reboot was clean.
On the second reboot there was a warning message about the BIOS
detecting "Inconsistent Timestamps" on one of the drives and something
about which CONFIG the BIOS would use.  I didn't have time to get it
all jotted down.  Whatever it used was still okay since the RAID
mirror was still there after that message.

If you need access to the system, a network kvm is available - or if
you have a C600 based system, you should see the same problem there.

Okay, and to confirm, this is happening on other C600 based systems.
Boot to Linux with MDADM raid support and the raid is gone after
reboot.

Hello,

I built a new system, installed new drives (no partitioning, just raw
new drives), configured RAID 1, boot to linux, created reports
attached.  Rebooted and the system doesn't see any configured raid
drives (just the two raw drives).

Thanks.  I might take a look, but I would greatly prefer it if you kept the
linux-raid list on the Cc.....

I must confess that I haven't even looked at it.
But I just saw and email on linux-raid from Martin Wilck:

 Subject: [PATCH] DDF: _write_super_to_disk: fix anchor header type

which very likely fixes your problem.  I've applied it and pushed out to
   git://neil.brown.name/mdadm/
