amd64 host kernel lock after some time

[tekknokrat]

I made several testings on ubuntu gutsy amd64 with feisty server (image-i386) and always my host freezes. This happens after some time aproximately an hour.

Before I can really do anything like shutdown, restart compiles some packages...
Also tried with with disabled apic on guest and running the guest headless (vrdp).

I preferedly would make a bugreport but perhaps there are some wellknown issues which I missed - investigated several hours in forumreads...

hm seems I am the only one with that problem.

I moved to another machine (amd tyan am2) with the hardy kernel (2.6.24-4) and no hardlocks of the host appears until now.
If somebody is interested I would also test with downgraded kernel to get the same behaviour like on my opteron 940 system.

But I got sometimes locks from the vm (ubuntu feisty) which are imo mostly related to network. Next time I'll see if i can fetch the kernel messages.
