So you are running an FC kernel on CentOS or RHEL? Or running FC anyway?

Thanks for the link, Andy. Didn't sound that similar in the beginning. I tried 
to repro those network transfer issues and couldn't. But the keyboard repeat 
stuff reported later sounds "promising". Seems there were really two problems 
mixed in one report.

None. After reading the bug report I added report_lost_ticks to grub.conf and 
rebooted, but still no errors in dmesg. Is my understanding correct that 
report_lost_ticks enables reporting in dmesg or logs or is it something else? 
Hm, according to Google it's exactly for this. Do I need to add something, 
f.i. "report_lost_ticks=1" or so?

Hm, a few minutes later.
The problem wasn't very apparent over the last hours. After an ntpdate it 
differed about 2 seconds within a few seconds and basically stayed that way, 
no increase or at least no noticable increase. Maybe it jumps from time to 
time to "achieve" a greater skew. However, now after rebooting with 
report_lost_ticks there's almost no difference. Hm. And, wow, I changed to 
runlevel 5 and the keyboard repeat problem is gone! I hope that really cures 
it, great!

And another few minutes later. Time is still okay, but maybe it's too early 
for that. But the keyboard repeat problem is back. Not as bad as before, 
though. Weird.
