Denis, I've seen similar issue with ACPI on my HP 6710b. Escape to debug and return doesn't help. Sometimes helps disconecting AC line. The workaround is comment out the following line in GENERIC: #options PREEMPTION # Enable kernel thread preemption #options ADAPTIVE_GIANT # Giant mutex is adaptive. Rebuild kernel, reinstall, reboot. Regards, -- Roman
