computer frozen

Hello

since kernel 2.6.28 or 2.6.29, I don't remember exactly, whenever I try to run KVM in my laptop, I get my computer totally frozen.

I'd try:
- "-no-kvm" flag: works, but very slow
- "-cpu qemu32,-nx": frozen
- "-no-acpi" flag: frozen

I'd try with several kernels (ubuntu and openssuse kernels), also with custom kernels compiled by me (with the minimal options enabled)....but always the same result: computer frozen

An interesting point: with Sun VirtualBox 3.1, the same frozen result.

My laptop is a TOSHIBA TECRA S4 (europe model only).

Anyone can help me?

Thx in advance.

It's been a long time since KVM caused host lockups. That is almost always something hardware/bios/local config related.
