Can > you capture the output of 'top -S' when your system is idle? It's not exactly reproducable since I have multiple oddities with ULE and=20 KDE. I also saw 2k lapic irqs/s with 98% idle, so it's probably not a=20 lapic problem. Is there any information about lapic available? I don't=20 know what lapic stands for (the l, if apic means=20 AdvancedProgrammableInterruptController) and what it does to generate=20 2kirq/s.
