It does. It seems to depend on the interrupt frequency : Setting KERNEL_HZ=250 makes it ony appear once a month or so, with KERNEL_HZ=1000, it will occur within a week. It does happen a lot less with the other machine, which isn't under disk activity load as much as the other machine.

Well.. It's too much coincidence that 2 (almost identical) machines show the same weard behaviour. What strikes me that only *disk* interrupts after a while don't get handled. The machine itself is alive, just all disk IO is blocked, which makes it pretty much useless.
Erich, could this be some sort of hardware problem ? I know it's a PITA to reproduce, but setting CONFIG_HZ to 1000 and bashing the machine with diskactivity seems to help :)
