The reason is there is a problem loading rtc-cmos. I will say that my machine also runs Windows, and it detects the device fine as a Real Time Clock/CMOS driver at io range 0070-0071. According to /proc/ioports rtc is probed at 0070-0077. During boot we get the following when attempting to modprobe rtc-cmos: root@excalibur:/usr/src/linux-2.6# dmesg|grep rtc drivers/rtc/hctosys.c: unable to open rtc device (rtc0) rtc_cmos 00:09: i/o registers already in use rtc_cmos: probe of 00:09 failed with error -16 root@excalibur:/usr/src/linux-2.6# this has happened with the stock kernel that came with my distribution, as well. Apparently you can only use 0070-0071 for my rtc? how can I get the device to work? here is /proc/interrupts: CPU0 CPU1 0: 23106 13272660 IO-APIC-edge timer 1: 49 5781 IO-APIC-edge i8042 8: 0 1 IO-APIC-edge rtc 9: 159 9301 IO-APIC-fasteoi acpi 12: 1818 190257 IO-APIC-edge i8042 14: 0 35 IO-APIC-edge ide0 17: 2174 312677 IO-APIC-fasteoi nvidia 18: 363 27432 IO-APIC-fasteoi HDA Intel 19: 1914 283347 IO-APIC-fasteoi ndiswrapper 20: 6434 1328206 IO-APIC-fasteoi eth0 21: 0 0 IO-APIC-fasteoi ohci_hcd:usb2 22: 0 0 IO-APIC-fasteoi ehci_hcd:usb1 23: 209 19944 IO-APIC-fasteoi sata_nv NMI: 0 0 Non-maskable interrupts LOC: 13272488 22989 Local timer interrupts RES: 105913 91197 Rescheduling interrupts CAL: 151 134 function call interrupts TLB: 18445 19521 TLB shootdowns TRM: 0 0 Thermal event interrupts THR: 0 0 Threshold APIC interrupts SPU: 0 0 Spurious interrupts ERR: 0 -- View this message in context: http://www.nabble.com/hwclock---systohc-locks-machine-up%2C-RTC-conflict-problems-tp14245613p14245613.html Sent from the linux-kernel mailing list archive at Nabble.com.
