Last night, after about 3 hours of listening to Oggs with XMMS and some
intermittent editting with vim, I noticed my mouse starting to get jerky
again and random keys on the keyboard would start repeating every so often
(even with fingers off the keyboard, those darn letters just a keep on
comin').
It might not be relevant, but the stickiness and jerkiness coincided with
the fan coming on to cool the extremely hot laptop. I think I also
plugged the power in sometime near the problems happening.
The problem happened in both X and a virtual console. Rebooting into
Debian didn't change anything, which suggested I might just have melted
some hardware. However, rebooting into Mac OS X (these were all soft
reboots BTW) gave me a working keyboard and mouse, and they continued to
work after booting back into Debian (with the fan still on and the laptop
still v. hot).
Is this some sort of odd kernel / PMU interaction bug? Could Mac OS X be
sanitising something in the hardware that fixes the problem under Linux?
Truly weird.
