Comment 31 for bug 89746

I tried recompiling the Gutsy 2.6.22-9 kernel with all RTC options completely disabled. Unfortunately, it didn't seem to change anything for me. On bootup with "noapic noirqdebug" I still had over 65% CPU usage in hard interrupts (according to top). When I booted without those flags, the machine hung during boot again and was non-responsive to the keyboard.
