but anyway I got some xen messages which *might* be helpful to you to give you
a clue what's going on^H^Hwrong anyway.

No - as long as only foreign (non-SuSE) guests cause these messages, we'll have
to direct you to the provider of those kernels. These messages indicate
something wrong in their kernel (seems like pages used as page tables don't get
cleaned up properly).

(XEN) mm.c:767:d6 Error getting mfn 90c47 (pfn 3623a5) from L1 entry
0000000090c47061 for dom6
(XEN) traps.c:466:d6 Unhandled invalid opcode fault/trap [#6] on VCPU 0
(XEN) domain_crash_sync called from entry.S
(XEN) Domain 6 (vcpu#0) crashed on cpu#0:
(XEN) ----[ Xen-3.3.1_18546_20-0.1.1 x86_64 debug=n Not tainted ]----

Still - not enough info for analysis (you cut off the register/stack dump,
which is the really important part if we want to understand what causes those
crashes - with the above I can only guess that the guest kernel hit a BUG()
somewhere). I'd suggest just providing the full log collected over serial.

With you stating that you can't reproduce the original behavior anymore, I also
wonder how reproducible your problems are in general (both with regard to
successive sessions on the same machine and between different machines).

And please attach logs or more-than-a-few-lines fragments of them rather than
putting them inline.
