    Doesn't seem to make a difference, sorry.

    For what it's worth, adding the iwlwifi-5000-2.ucode to the builtin firmware
    list fixed the two BUG: messages related to the firmware load. Not sure if
    that tells you anything or not.

    However, I still have left:

    [ 0.997904] Monitor-Mwait will be used to enter C-1 state
    [ 0.998045] Monitor-Mwait will be used to enter C-2 state
    [ 0.998184] Monitor-Mwait will be used to enter C-3 state
    [ 0.998300] Marking TSC unstable due to TSC halts in idle
    [ 0.998476] Switching to clocksource hpet
    [ 1.030681] BUG: key ffff88011c8c1d00 not in .data!
    [ 1.030787] BUG: key ffff88011c8c1d48 not in .data!
    [ 1.035288] thermal LNXTHERM:01: registered as thermal_zone0
    [ 1.035405] ACPI: Thermal Zone [THM] (54 C)
    [ 1.041622] Real Time Clock Driver v1.12b
    [ 1.041955] Linux agpgart interface v0.103
    [ 1.042266] Hangcheck: starting hangcheck timer 0.9.0 (tick is 180 seconds, margin is 60 seconds).

    I'll stick a 'WAR_ON(1)' next to that BUG printk so we get an idea where it's
    happening, probably be morning before that happens though...
