Indeed, I tweaked one BIOS setting, I disabled hyperthreading.
The R410 BIOS has a CPU menu with (among other options):
- Logical Processor: this is 'HT', default is enabled, I have disabled
it.
- Virtualization Technology: default is disabled. Kept disabled.
- Number of Cores per Processor: default is 'All'. Options are
single/dual/all. Kept 'all' defalut.
I just tried to boot Xen 4.0 hypervisor after reverting to the factory
default 'HT enabled' (aka Logical Processor: Yes), same bug.
Then I swithed off HT again, and enabled 'Virtualization
Technology' (setting which I totally overlooked, but why is it disabled
as default ?). Same bug.

OK, should I pick the one in
http://xenbits.xen.org/people/ianc/squeeze/ ? (I'm running Debian
Squeeze on this machine)
