JB> JB>This just looks like you aren't getting interrups from devices at all. Why do you think so? This case has happened in the middle of boot even before disks were started and the kernel hasn't printed anything about disks it has detected. It looks normal to me that just a few interrupts has been triggered. But irq9 looks quite suspicious, isn't it? Can it be possible that by some reason interrupt storms are triggered on different irq lines resulting in different behaviour? -- Oleg Sharoiko.
