Unfortunately the clock drift still occurs with pata_pdc2027x. I'm guessing here, but can clock drift have anything to do with IRQs? Also, is it normal to see errors in /proc/interrupt? # cat /proc/interrupts CPU0 0: 954189 XT-PIC timer 2: 0 XT-PIC cascade 8: 16 XT-PIC rtc 9: 0 XT-PIC acpi 10: 1630 XT-PIC eth1 11: 103147 XT-PIC libata 12: 9990 XT-PIC eth0 14: 5993 XT-PIC ide0 15: 145866 XT-PIC libata NMI: 0 LOC: 0 ERR: 23672 MIS: 0 Regards, Oskar Liljeblad (oskar@osk.mine.nu) - 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/
