------- Comment #42 from [EMAIL PROTECTED] 2007-11-24 06:22 -------
Between the two snapshots I got a hung key, for example PagUp or PagDown, and
the release key event was lost, as seen in dmesg.
At least 2-3 seconds elapsed, as I had to press some keys, check dmesg|tail and
then do dmesg>dmesg.after (you can check the file timestamps).
$ grep HZ .config
CONFIG_NO_HZ=y
# CONFIG_HZ_100 is not set
# CONFIG_HZ_250 is not set
CONFIG_HZ_300=y
# CONFIG_HZ_1000 is not set
CONFIG_HZ=300
When using 2.6.22 I had 250 Hz instead, and the problem (iirc) happened more
frequently.
'cat /proc/interrupts; sudo modprobe thermal; cat /proc/interrupts' did not
work. I will try again, with some luck I will succeed.
I also think that the global lock should be really infinitesimal, but since my
keyboard interrupts can get in the middle - it must be somewhat longer, I guess
it can sometimes reach a maximum value in the order of 0.5s/0.8s
I am going to test the patch in comment #40 ASAP
Thanks
