2.6.16-rc3 kernel BUG at drivers/scsi/sata_mv.c:1018

[Sander <sander@humilis.net>]

Hi Jeff and others,

I get a kernel BUG message when I try to create a raid1 or raid5 over
nine 64MB partitions located on nine sata disks (Maxtor Pro 500) on a
fresh setup. The system locks hard: no sysrq.

The onboard controller is an nVidia nForce with three disks.
The six other disks are connected to a Marvell 88SX6081 controller.

Last night and the first half of today all disks were tested with
badblocks in write mode, which the system survived just fine (one disk
out of ten detected as broken, so nine disks left).

A google search leads me to

http://www.uwsg.iu.edu/hypermail/linux/kernel/0601.2/0479.html

and

http://www.uwsg.iu.edu/hypermail/linux/kernel/0601.2/0626.html

I had MSI disabled in the .config already, and will try again with debug
options set.

In the mean time, is this of any help?

I can try any patch you throw at me, or any config option, as this
system is not in production yet.
