Under BIOS 1.36, Ubuntu 12.04 Beta2, Linux xxxx 3.2.0-21-generic #34-Ubuntu SMP Fri Mar 30 04:25:35 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux, the problem still occurs.
Indeed, with the nox2apic kernel option, I can still enable VT-d, nvidia 295.33 and things stay stable.
But whats is impact of nox2apic ? That you have to keep devices running with less IRQs ?
