Bug Description

Binary package hint: linux-image-2.6-686

My pc
Carte mère msi 865pe Neo2-p
1 G0 de ram
Carte video ati radeon 7000/ve
Cpu intel prescott 3 Ghz
Carte wifi evo-w54pci
With Breezy no pb (linux-image-686).

Same pc with 6.06LTS (Linux-image-686) in console mode no pb but with Gnome freeze after 2 mn.
This morning I do this test:
I desactivate in Bios HyperThreading, then I boot with Linux-image-686.
The pc work fine.

Check list:
#more /var/log/kern.log | grep SMP
