Kernel Patching
In my recent PowerTOP adventures I discovered a few timers which could be removed. One was a polling loop in the PCMCIA driver, which I disabled because the interrupts are unreliable, apparently. This turns out to be totally correct, with the polling disabled it doesn't notice me inserting a CF, so I can't do anything. I'll leave this on the "something to pester Richard about when he is less busy" list.
The next driver related poll on the list was from a IrDA module. Now, it shouldn't be doing anything because I have nothing apart from the drivers loaded. Even unloading the real drivers and just loading irda.ko caused wakeups, so I hunted around and with lots of Samuel's help (he took my concept patch, and made it actually compile!) we produced a patch which was merged into David Miller's 2.6.25 tree today. Excellent, I'm now a kernel hacker!
