This time it just started sometime after boot. The scheduler class of the different irq's seems to have no influence [i experimented with SCHED_FIFO and SCHED_OTHER for irq 1, 8, 12 and 3 and 10 [the latter two are my soundcards irq's]. ~$ cat /proc/interrupts CPU0 0: 480317 XT-PIC timer 0/80317 1: 1731 XT-PIC i8042 0/1731 2: 0 XT-PIC cascade 0/0 3: 10828 XT-PIC CS46XX 0/10828 5: 390 XT-PIC eth0 0/390 8: 4 XT-PIC rtc 0/4 10: 251556 XT-PIC SiS SI7012 0/51556 12: 16605 XT-PIC i8042 0/16604 14: 1151 XT-PIC ide0 0/1151 15: 26537 XT-PIC ide1 0/26537 NMI: 0 ERR: 0 Btw: i just experienced two pauses again, so the patch didn't really fix it :( hrmm.. I get the feeling that something indeterministic is going on. Still no BUG's in either dmesg output nor in the syslog. flo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
