[Xen-devel] xen-swiotlb

[Sander Eikelenboom <linux@xxxxxxxxxxxxxx>]

Hi Konrad,

After i have exhausted all kernel debug options without getting a pointer to my 
freezes, i have added some printk's to all functions in swiotlb-xen.c
I see a lot of calls to xen_swiotlb_dma_mapping_error, which doesn't seem to be 
good ?

Although all the errors the device works fine (grabs video), but eventually the 
machine freezes, probably due to overwriting some mem it shouldn't.

Could you have a look at it ?
