Comment 38 for bug 89746

I have run some more bootup tests. I am now booting with the options "noapic irqfixup" instead of my previous "noapic noirqdebug". My system runs very stable with either of those, but there are fewer spurious ehci interrupts with irqfixup. powertop shows the ehci interrupts drop from 450 per second to 250 per second with irqfixup.

I have also found that the LiveCD of SimplyMEPIS 6.5.02 (64-bit) boots fine on my system. I believe it is running kernel 2.6.15. Perhaps an attempt at bisecting the differences between that kernel and the current version will yield what changes are causing the problem.
