Hi my 2xP-II@400MHz locks up with 2.6.32(.X) unless I specify "idle=*" on the kernel command-line, where "*" is one of "poll," "mwait," "halt," and only "nomwait" indeed locks it up. Last kernel known to work was 2.6.25. So, it doesn't bother me all that much - I have a way to boot it, but maybe someone would be interested to fix this (this system already has a few quirks on the kernel command line, so, one more doesn't really hurt;)). What interests me more - which of those shall I be using? From Documentation/kernel-parameters.txt it looks like "mwait" should be best for me? Or should I be using "halt?" "Poll" does indeed fry CPUs - raises sys temperatures to 50 / 60 degrees C. Power-saving is not that much of a concern for me - I only run that system occasionally, but it shouldn't produce more heat than it must;) And since this system does have a broken ACPI (Compaq AP400), I wouldn't try to be too smart with it.
