2.6.33 works for me with the default settings, but if I try to active
MSI for my sata ports, writes to my hard disks start to fail.

MSI support was added to sata_sil24 for 2.6.33 with commit
dae77214fa71898b84514e43721fb7bf260b026a .
MSI support for sata_nv is older (commit
51c8949950647afeeb897e08dd75ad99078adb50 ), but today I retried it an
it also fails.

Both default to off, but can be easily actived with sata_sil24.msi=1 /
sata_nv.msi=1.

My system itself should support MSI, as my network cards (2x tg3) and
video card (X300 radeon) do work correctly with MSI enabled.

Differences from the dmesg for sata_sil24:

The system starts to boot, but early in the userspace boot sequence
(probably after the first write accesses) access to the disks fails:

The system has 4x 1GB RAM sticks (2 on each CPU).
And there is no line like 'EDAC PCI0' for the DRAM controller of the
second CPU (19.2). Is that normal?
