Comment 1 for bug 134092

I am experiencing the same. But I am also experiencing random lock ups. Usually after a couple of days running. Powering down seems to be the only fix it as the system will not unlock (kscreensaver) and login seems to hang on the vts. I have been able to prevent the errors showing up by putting "noapic" as a kernel argument. But this disables the SMP. I really not sure if that will cause a loss of performance. (Not that up on the differences).

My Machine is a HP Compaq 6715b Laptop running a AMD Turion(tm) 64 X2 Mobile Technology TL-64 stepping 01 Dual Core.
