[Xen-bugs] [Bug 1698] Xen dom0 crashes immediately after boot



http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1698





------- Comment #2 from at@xxxxxxxxxx  2010-12-20 08:30 -------
Another R710, being an exact clone of this configuration crashes as well. 

Some older machines (~ 2 months), again being R710 but having a slight
different configuration (< 2TB disk thus using DOS partition tables, slightly
different CPU, RAID controller and no SAS disks) don't have this problem. They
run Debian stable (thus and old style dom0+hypervisor with Xen 3.2). The output
may therefore not being that useful, however:

Debian stable failed on the crashing machines as well, although I cannot
remember exactly what the problem was. If you do care I can reinstall on of
those machines with Lenny/Xen 3. 

Let me know if I can further assist you. I may also provide you or someone
being interested to dig the bug command line access to the machine if you want.
