After activating the MSI support by adding sata_sil24.msi=1 to the
kernel command line, the first write to a drive attached to the SiI
3132 controller results in the following errors:

This repeats for a large number of times, then the XFS filesystem gets
shut down.

More information about my system are in my first report:
http://lkml.org/lkml/2009/12/19/82

lspci -vv for both the normal, working and the broken MSI case are in
my second try to report this:
http://lkml.org/lkml/2009/12/25/12

Please ask, if you need more information.

Hi Leon,

I have the same problem with the sata_sil24 driver,
using SiI 3132 and enabling msi causes an nmi.

http://marc.info/?l=linux-ide&m=129138342901236&w=2

Can't there be a workaround for this errata?

The sata_sil24 interrupt is shared on my system with
an cx88 tv card which often produces an irq storm.

-Tobias
