It seems from 2.6.21 the problems are mainly about 'older' network chips on x86_64. This reverted patch should mean only for those using disable_irq, but I see forcedeth could use this too so it's not clear yet, and btw. there where other changes around irqs and pci, so everybody could have something a bit different with similar time outs logs... BTW, Jean-Baptiste and Chuck - it seems, unless you have too much time, there is no use for testing my "genirq: fix simple and fasteoi irq handlers" patch.
