No, and no. Where's that fix? On that topic: do you publish your bk
repository directly, or should I keep pulling from Linus' tree? (Last
Friday, that one was broken due to DaveM's networking updates :-() What bk
tree would you like to take diffs for?

Maybe time to be more specific WRT sensor and fan location in the driver.

Seems to lock up more reliably in 2.8.9-bk indeed. I have HIGHMEM off (or
pmdisk wouldn't work). The thermostat fix was only tested on 2.6.8 though.
Need to repeat that with 2.6.9 now.

I've run a full x11perf with no lock up. No idea how else to trigger the
lock (seems to be related with fast scrolling in either xterm or mozilla).

Lucky duck. I need to upgrade RAM before that is an issue :-)
