Re: [2.6.25-rc1] jerky mouse cursor and randoooom key repeats
Jiri - For what it is worth, and understand that it is hard to prove a negitive, on slack moments over the weekend I repeatedly booted my system into single user (console) mode using a kernel with CONFIG_GROUP_SCHED set to yes. To date I have NOT been able to recreate the repeating key issue outside of X.

Hmm, I have been seeing repeated keys a lot under X on my athlon 700, but mainly when I have firefox running (which is of course quite a load on the poor old thing). This has been going on for probably the last year or so. I thought it was just the machine getting weird, although whenever it wasn't running firefox or other memory/cpu heavy loads it seemed fine. The USB bus also keeps detecting and loosing a USB hub again and again, so perhaps that is also a software problem and not actually the hardware failing.

I am now up and running on 2.6.25-rc2 with CONFIG_GROUP_SCHED not set (and for the record, I did NOT use the nohpet directive when booting) A copy of the dot-config file from this build has been inserted below. So far everything is working nicely with CONFIG_GROUP_SCHED not set. However I have one observation to make, and I am very likely missing something here, is that over the past few days while I have been trying to isolate a broke / not broke point with git bisect it would seem that the conditions which lead to the repeating key failure are seeded at the time of the boot. By this I mean that given a specific kernel configuration I can boot it 'x' number of times - out of all those boot cycles I may get one instance of the failure. The rest of the time it works fine. On those occasions when I do get the repeating key failure it would appear that the failure lives for the lifespan of the boot. Twice now when I have had the failure I have tried restarting X to see if it clears, but so far I have not had any luck with that. I have compared the dmesg output from a good boot to that of a boot where I see the repeating key issue and except for the expected minor differences in the timestamps nothing jumps out at me. I built the kernel you requested with the '-j2' option to load up the CPU - I thought that the suggestion made earlier by someone else about this failure happening while the CPU was loaded had some merit - it was one factor I did not take into consideration during my efforts and might explain why I was getting inconsistent results. However, even though both cores were running along at nearly 100% during this build, I did not see the problem. At this point I am about ready to select a previously unused section of wall to bang my head against.

Re: [2.6.25-rc1] jerky mouse cursor and randoooom key repeats
Frans & Pavel;
I too saw the random key repeats you are seeing with 2.6.25-rc1 -
however, I saw it (or something very much like the problem you are
reporting - I am not smart enough to determine if the root cause is the
same) with 2.6.25-git15
A number of corrispondents on this list offered troubleshooting
suggestions, most of which centered arund the high performance timer.
If you too feel that the issue you are seeing might be releated to the
one I saw the following clips from the email I received might be of
interest to you.
>From Jiri Kosina:
It could be some timing problem. Does this happen also in console, or
only when running X?
Could you please try to
- boot with 'nohpet' kernel parameter
- taskset -p 0x0002 if this is a multi-CPU/core
machine and you are experiencing the problems only in X

I have been trying to narrow it down using bisect (my first attempt at
using this utility) with mixed results - just when I think I understand
where the problem was introduced I hit a brick wall.
However, you comment on system loading may have turned the old light
bulb on - that is one area where I have not been consistant.

I was wrong :-( I'd not really done any real wor under 2.6.25 yet, but now while running a kernel compile with -j4 (single processor, dual core Pentium D), I see this behavior. The mouse cursor moves a bit jerky and I sometimes get key presses repeated. While I'm typing this, the load lowers a bit and immediately things become smoother and the key repeats seem to vanish.

The keyboard repeat issue looks like what was reported in [1], but for me this is very definitely an new issue that did not appear with 2.6.24 or earlier.
