Then why would I be seeing flakiness including one kernel "temp too high" message just before an automatic shutdown? But it's true, I've been assuming temp is the problem because the shop reports 68 C is above what they believe is rated (40 - 50) and because that's when the fun starts. -- Lan Barnes SCM Analyst Linux Guy Tcl/Tk Enthusiast Biodiesel Brewer -- [EMAIL PROTECTED] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
