Could you show me this? # acpidump | grep SCI_INT Also, I'd like to see which acpi event was occured on ramdom sleep. Backtrace is helpful to track this down. Press Ctrl+Alt+Esc into DDB, enter db> b acpi_SetSleepState to set break point, then send me the output of db> t when the ramdom sleep is occurred. BTW, you can set ignoring some of acpi events like this: # sysctl hw.acpi.power_button_state=NONE # sysctl hw.acpi.sleep_button_state=NONE # sysctl hw.acpi.lid_switch_state=NONE > acpi0: <RCC RCCNILE > on motherboard # I worry about this... :P Thanks To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
