With 2.6.25-rc6-git-something I have experienced stuck keys. When typing a sentence a character repeats aboooooooout 10 times, or as 'about' above ;). I tested with a new kernel today, 2.6.25-rc7-git-something and the problem is still present.
With 2.6.25-rc3 the keyboard is fine, and I've not tried with any kernel in between.
As a side note, timestamps gets mixed up in dmesg output in a 1-2 second span. Maybe related?
This is on a HP dv2140eu laptop, x86_64 SMP. Please cc me if you want configuration details or testing to be done.
