AM>=20 AM> I guess I'll drop the patch for now in that case. I somehow doubt that the HPET patch itself is the culprit. In fact, the reason it shows up on git-bisect is probably because without it HPET functionality is not enabled on the platform. So the problem could really be anywhere in the HPET-driven timer infrastructure. Frans, could you try out the -hrt patchset from Thomas Gleixner and see if that works? Also, what ICH does your platform have? ICH3 or ICH4? Cheers, - Udo --Sig_/af94/YuftBS8YMX65YwFst.
