2.6.23.1-rt5 rtc lost interrupt

2.6.23.1-rt5 rtc lost interrupt

[Dragan Noveski]

hallo list, yesterday strange thing happened here.
i am running 2.6.23.1-rt5, and actually it is running good, but 
yesterday partially my keyboard stopped working. usually if i press any 
key (inside of xterm) and do not release, but keep pressed, the 
letter/sign will be printed all the time again and again as long as i 
release the key.
something like:

aaaaaaaaaaaaaaaaaaaaa

but yesterday, if i was holding the key, the letter got displayed on the 
screen just one time.
if i released and pressed again, one more time.....
so i was not able to press only one time a key and hold to get sth like 
these:

........................

than in /var/log/system i found this lines:


Oct 30 21:22:37 murija2 kernel: rtc: lost 8 interrupts
Oct 30 21:22:50 murija2 kernel: rtc: lost 4 interrupts
Oct 30 21:22:50 murija2 kernel: rtc: lost 20 interrupts

this also appeared in dmesg.

is this explained so that someone is able to understand?
does any one has an idea what went wrong here?

after a reboot the keyboard was working as usually again and the issue 
did not happened again since them.

hope to get some suggestions/answers?!

cheers,
doc

What X drivers are you running (hopefully not nVidia or some other
proprietary module).

Unfortunately, this gives me no clue to what went wrong. Perhaps, you have
a high priority process running somewhere that is keeping things from
running.

What type of system is this? SMP?

no it is perhaps one of these both:

00:02.0 VGA compatible controller: Intel Corporation 82852/855GM 
Integrated Graphics Device (rev 02)
00:02.1 Display controller: Intel Corporation 82852/855GM Integrated 
Graphics Device (rev 02)

...but nothing proprietary here.

ok, but this gives me an idea, because i was just backtracing 'aqualung' 
and 'bristol synth emulator' and letting them crash again and again.
but i was not thinking that this could be causing the issue.

i was expecting that the info i had is not info enough!

anyway, it did not appeared again, so i will not be scared too much now, 
if it comes again, you ll hear from me.
