This just happened to me again. I did /etc/init.d/acpid stop, and it did, but issuing halt left me with the acpi_power_off called message. I think some memory corruption may happen in kernel space, or it is just ACPI failing for some reason. If this helps, I can say that this bug happens slowly, first I just realise that more and more CPU time is being used; say 6% user space and 14% kernel space from looking on a gkrellm display while my system is completely idle. It goes up to 48% user space and 49% kernel space CPU usage causing the box to crawl (load also goes up, usually it's ~3.0 - ~5.0). So if I see this happening, I act quickly, logout from GUI, and issue halt from console; still in these cases the box can not halt, but display acpi_power_off called. Also not that I have this for a long time, if memory serves me right, then I have this with all 2.6.x versions and with late 2.4.x versions as well. Let's wait on 'dev_zero' if s/he has the very same symptoms or not. Also if I can do anything, say running a modified acpid which logs an extra amount of debug log, please tell me. Otherwise I can not directly reproduce this problem. :-( Cheers, Laszlo ------------------------------------------------------- This SF.Net email is sponsored by: Sybase ASE Linux Express Edition - download now for FREE LinuxWorld Reader's Choice Award Winner for best database on Linux. http://ads.osdn.com/?ad_id=5588&alloc_id=12065&op=click
