Re: [Xen-devel] kernel BUG at arch/xen/i386/mm/hypervisor.c:99!
I am having a similar problem with xen 2.0.3. 2.6.10 in dom0, and
2.4.28 in dom1. Compiled the openafs kernel module, installed, insmod,
etc... After a minute the console spews:
Failed to execute MMU updates.

And the virtual machine eventually becomes complete unstable (will not
shutdown properly).
I have enabled kernel debugging, but the symols are not being resolved
for some reason. Any help would be appreciated.

Running more SMP tests, using -unstable from 2005-01-25:
2.6.10 w/ CONFIG_SMP dom0 and multiple CONFIG_SMP domU domains (2) with
vcpus (4 and 1 respectively) and encountered this inside a domU kernel
(4 vcpus).

after this, both domUs are dead, though dom0 is still alive.
