This is the third SB600 system which can't do 64bit DMA. Add it to blacklist. Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: Holger Hasselmann <hhasselm@web.de> Cc: Shane Huang <Shane.Huang@amd.com> --- This is bad because we can't backport this to -stable and broken 64bit DMA makes these systems unusable for kernels released without the following blacklisting. I think we should disable 64bit DMA for SB600s in -stable. Any objections?
