Hello,

it seems my problem is also related to the mvsas driver/scsi subsystem:
http://thread.gmane.org/gmane.linux.kernel/1150608

I can reproduce the problem with a simple:
dd if=/dev/zero of=/dev/sdc

I tested this with the newest stable kernel 2.6.39.2 and two different
enterprise SATA drives:
* Seagate Constellation ES
* Hitachi Ultrastar 7k3000

I'd like to help debugging this.
Please give some instructions.

Lars
