Comment 257 for bug 355155

Disabling multicore support does not solve my problem. I've changed it yesterday and it worked w/o freeze. Today after wakeup from hibernation, I got a freeze while logging in.

@Chem.Imbalance: I'm happy for you but I don't see an IRQ conflict on my side

I did not yet a kernel upgrade:
Linux clawfinger 2.6.28-13-generic #45-Ubuntu SMP Tue Jun 30 22:12:12 UTC 2009 x86_64 GNU/Linux

Btw. I never had freezes with 32bit version of Ubuntu Jaunty (used since alpha 4).
