[Xen-devel] DMA in HVM guest on x86_64

[Michael Best <mbest@xxxxxxxxxxxxx>]

I've been following unstable day to day with mercurial but I'm still 
having a problem with my HVM testing.
I using the i686 Centos + Bluecurve isntaller and I get the following 
error in the guest during disk formatting:
<4>hda: dma_timer_expiry: dma status == 0x21
<4>hda: DMA timeout error
<4>hda: dma timeout error: status=0x58 { DriveReady SeekComplete 
DataRequest }
<4>
<4>ide: failed opcode was: unknown

Not sure if there is a solution to this at present, or if some patches 
are still coming down the road.
