Public bug reported:

Think there is a Linux kernel bug.

I have an Asus P5Q Premium with SIL5723 and I guess Marvell drivers
(61xx / 88se6121). Everything was working nice when running 10.04. After
installing 10.10, Ubuntu would not recognize disks on the SIL5723. I
have part of a Raid 6 on these connectors. ICH10 disks no problems.

Disks are recognized by BIOS and I see disks (DriveXpert when starting
the PC. When booting it takes a lot of time and then I get message about
raid not mountable.

Started 10.10 with kernel 2.6.32 and raid mounted and working perfect.
Guess 2.6.32 is long term stable release. However with this kernel I'm
not able to run Gparted and there might be other problems as well. Guess
2.6.32 was available for booting as I upgraded and did not do a fresh
install.

Looks this is a Linux kernel (2.6.35) problem. I'm not able to find
Marvell drivers to install. Not keen on going back to 10.04 either.

When running “lspci” I find the  88SE6121 both for 2.6.32-25.44 and
2.6.35-22.35.

I have attached “dmesg” for both runs (in the same file). Disks on
DriveXpert are recognised when running 2.6.32 but there are no reference
to that controller when running 2.6.35.

Best regards
Per Arne
