Re: data corruption with nvidia chipsets and IDE/SATA drives // memoryhole mapping related bug?!

Hi folks.

1) Are there any new developments in this issue? Does someone know if
AMD and Nvidia is still investigating?

2) Steve Langasek from Debian sent me a patch that disables the hw-iommu
per default on Nvidia boards.
I've attached it in the kernel bugzilla and asked for inclusion in the
kernel (until we find a real solution).
I'd be pleased if all of you (who experienced the data corruption) could
test this patch.
Note: This patch is NOT a real solution for the issue, it just applies
our workaround (iommu=soft) per default

Bugreport at kernel.org: http://bugzilla.kernel.org/show_bug.cgi?id=7768
Bugreport at Debian: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=404148

Best wishes,
Chris.
