I've been booting with "acpi=off", but I'd rather have it enabled and not causing this problem. The kernel is compiled WITH the ACPI-PM timer support. Perhaps I should try building one without that? HPET is very new, am I correct? This laptop does not seem to have one. Would the "unsynced tsc support" option (2.4) affect this? IO-APIC? I really need to find out what class I need to take where they'll teach me what all that stuff means! It's embarrassing to have been around Linux this long and not know what that stuff is. Anyone know a good book where I can read about it? {Please.} First I will try to turn off the battery monitor in the gkrellm that I always have running. cpufreq is enabled even without ACPI, and it's working fine; Centrino enhanced. That does not seem to be the cause of the problem. -- If you feel like the machines are conspiring against you, then it's time to perspire against the machines. ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
