Hi,
This sounds a lot like my i386 system at the moment. Every morning I have to do a hard boot. I tried without ACPI and same result.~# ... sending BREAK does work.Me too. http://www.vex.net/~darcy/20120428_4307.jpg
Well, i386 case is rather surprise to me. Lockups are related with scheduler itself, not particular device or memory activity. Toru Nishimura / ALKYL Technology
