So a couple of things popped at when looking at this:
a). "sata_nv 0000:00:08.1: BMDMA: failed to set dma mask, falling back to PIO"
That is not good. Somehow it wasn't able to set a 32-bit mask. Don't know
if that is due to the driver or just that the kernel can't do it (b/c it
was compiled with some special options).
b). Are you using some special .config option? If you were to use a normal
distro would you see this?
c). You are using a 32-bit dom0. Didn't notice it until now so I wonder
if there are some lingering issues (for example not flushing the highmemory
mappings) that are at foot. Had you tried a 64-bit kernel before?
d). Does the problem exist if you try it with a 2.6.39 kernel or the 3.0-rc3?
e). Can you run lspci -n ? There is a pretty big file in
drivers/usb/host/pci-quirks.c
Want to check against your machine.
