Public bug reported:
Running 7 disk raid 5 array with the following card:
SCSI storage controller: Marvell Technology Group Ltd. MV88SX6081 8-port SATA
II PCI-X Controller (rev 09)
file system is XFS.
Trying to do a 'cp' from the system drive (IDE, XFS) to the raid would
constantly lead to the process stalling (state: D+) and leading to a
cold reset. I believe network transfers are also suffering from this.
Hardy wasn't reporting _any_ of these errors in dmesg or
/var/log/messages. Upgraded to Ibex to try and help track down what was
going on and got the following _when_ transferring to the raid.

I've replaced the card and cables and i'm still getting the issue.
This card&raid was working on a centos last week (2.6.18 32bit).
Replaced OS (ubuntu 64bit), cpu (core2duo), mobo (asus p5k pro)
other info:
1) ubuntu release:
Description: Ubuntu intrepid (development branch)
Release: 8.10
2) package versions:
linux-server:
Installed: 2.6.27.2.2
mdadm:
Installed: 2.6.7-3ubuntu4
Candidate: 2.6.7-3ubuntu4
I'm really at a loss here, not sure what else to do. I stressed the other
components of the system in windows and they seemed fine. not sure if its the
card or something with the newer kernels.
also, these issues are not causing my raid to fail.
