Re: [Xen-devel] Xen with dom0 pvops on ultra-recent "git tip" kernel on x86_64

Hmm, I found this patch in the SuSE kernel where they just return from
grab_swap_tokens if current->mm is NULL and claim that it can happen
(?).

Applying this makes the system happily continue past that point and
almost fully come up.  Hard disk working, wireless working, not looking
bad at all.

The X server however didn't want to start and crashed somewhere in
"vgahw" initialisation. (*)

Also, the console locked up after ~2 minutes, but still reacted to
Alt-SysRq-B.

I could produce some Alt-SysRq-T traces to see what's going on, maybe
using netconsole, but some other time.

Cheers,
        Christophe
