Hi, Martin,
I have checked your dump info via debug key. I saw that the EIPs remained
the same between two successive dump. However, without the symbols I could
not identify which code kernel was hanging on. Is it possible that you can
find this information by disassembling the kernel binaries (with symbols).
Or could you please repeat your test using an upstreaming Xen and kernel so
that I could compile a same kernel just as you would be using?
And I see you CPU is a very old model, UP without 64 bit support and no PAE?
Right?
