    I have put the idle=C1halt patch that Ross released a little while back
    now into Gentoo-dev-sources-2.6.3 as I reported to the list yesterday. I
    no longer use the old apic_tack=2 patch. I have been playing silly
    buggers with hardware, but so far the PC has made it to 11 hours and now
    7 hours with no issues.

    After those 11 hours I decided I'd change the PC setup in here and
    disconnected a fan and a hard drive and moved my server s/w (apache etc)
    to this PC so I only have one in here fpr now.

    Right now, CPU is at 34C which is only 1-3C higher than with the other
    patch, including having one less fan sucking air out the back of the
    box. Motherboard is actually lower (27C) than before (29C). Ambient room
    temp is normal.

    After those 11 hours, I am quite sure that on normal use (ie not
    compiling) the motherboard and cpu was 1-2C lower than with apic_tack=2.

    regards
    Craig
