Mine: [root@medulla ~]# uname -r 2.6.23.8-34.fc7 I wonder if this is a kernel bug? When I search in "/var/log/dmesg" for "Real Time" I get the following (with surrounding context): ACPI Exception (processor_core-0818): AE_NOT_FOUND, Processor Device is not present [20070126] ACPI Exception (processor_core-0818): AE_NOT_FOUND, Processor Device is not present [20070126] ACPI Exception (processor_core-0818): AE_NOT_FOUND, Processor Device is not present [20070126] ACPI Exception (processor_core-0818): AE_NOT_FOUND, Processor Device is not present [20070126] Real Time Clock Driver v1.12ac hpet_resources: 0xfed00000 is busy Non-volatile memory driver v1.2 Linux agpgart interface v0.102 Search on "clock" also turns up (with context): hpet0: at MMIO 0xfed00000, IRQs 2, 8, 0 hpet0: 3 64-bit timers, 14318180 Hz Time: tsc clocksource has been installed. pnp: 00:01: ioport range 0x800-0x85f has been reserved pnp: 00:01: ioport range 0xc00-0xc7f has been reserved pnp: 00:01: ioport range 0x860-0x8ff has been reserved I'm not sure what any this means. "hpet" is the "high precision timer" and the hpet_resources: 0xfed00000 is busy line is suspicious. I don't know what AE_NOT_FOUND refers to. Anyway, I'm at the end of my knowledge here, but would very much like to find a solution. Thanks for your help. Dean
