| |
Since 2.5.60 my thinkpad keyboard repeat rate has been erratic when started up on battery power; plugging into AC after startup only makes it worse. Starting up on AC is fine. Compiling without apm in any form is fine.
I posted on this a month ago and noone had solutions although I got several emails from folks with similarly afflicted machines.
Since then I've noticed that I also get a bad time skew, with the system clock jumping forward.
I'm pretty sure the problem arose with the introduction of the seqlock/unlock interface to protect xtime_lock instead of a regular rw lock. Short of trying to back the whole thing out, does any one have similar observations, suggestions, solutions?
