Could you make sure you compile in "Magic SysRq key" under "Kernel Hacking" and boot the vanilla-2.6.13-rc6 (some recent acpi changes have gone in) and then wait for kacpid to go nuts and do Alt+Sysrq+t 4 times and then run 'dmesg -s 100000 > logfile' and send logfile over here so that we can see what kacpid is up to. If the box becomes so unresponsive you can't extract the log information it would be good if you could use either network console Documentation/networking/netconsole.txt or serial console at Documentation/serial-console.txt, both require an extra computer though... ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf
