[Xen-devel] kernel BUG at arch/x86/xen/mmu.c:1649! and others ...
Hi Jeremy,
I'm still experiencing total freezes of my system when passing through a
device, and with most linux kernel debug options on in the guest i still don't
see a oops.
I do get these messages in dom0 on boot, although perhaps they are false due to
all the debug enabled.
For the freeze, i have enabled debug in xen, in xend config, put the on_crash
for the guest on preserve.
But still it freezes with this domU, all others just run fine, when i don't do
pci-passthrough it also runs fine.
I looked at the source of xen-swiotlb, but didn't see any debug i could enable
there.
