Greetings,
(I'm posting this to LKML and CK because I'm not sure if any of 2.6.15-ck1's
changes might cause this scenario)
Recently I've noticed that after my desktop has been up for a while, my music
playback / mouse cursor movement will on occasion pause briefly. I got
frustrated with it a minute ago and decided to kill artsd, wondering if there
could be issues with both arts and amarok's backend holding the audio device
open at once.
When running killall artsd, I locked up for a second and found this in dmesg:

AFAIK random page state toggling often happens due to bad RAM.
Care to run memtest86 or similar to confirm this?
Or also try running an older kernel to verify whether it doesn't happen there.
But I'm betting on bad RAM :-\

Andreas,
I've been looking into this problem a little bit more (did some digging to
try and teach myself a little bit about the page flags). I noticed after
posting that I had bad page states reported in dmesg for amarokapp (new ones)
as well.
So I got a bit curious and looked to see what bits were stuck on... and I
started to wonder if it could have something to do with ALSA. (Unfortunately
I'm quickly reaching the limit of my current understanding of the kernel's
innards)
Anyway, I tried a test - made sure both amarokapp and artsd were dead, then
used rmmod to pluck out every last "snd" module. I put them back in, fired up
amarok, and went to play a song. It played fine with no noticeable latency,
so I tried switching to another track. Doing so caused the system to freeze
for a few seconds and another set of bad page states to go rushing through
the log.
I can accept bad memory (though I think it's unlikely on this system because
I've tested that fairly recently) but the page states, while bad, are
consistently (not randomly) so.
I'd reboot right now and test it, but at the moment I'm capable of
reproducing these page state errors 100% of the time, so if there are any
sorts of things I can do to debug the thing while it's up I'd like to move
forward with that before I reboot and lose whatever 'ideal state' got me here
in the first place.
Thanks,
Chase

Ah ha! Well, this looks like it'll be a quick fix. I'm building ALSA-1.0.11rc2
now.

I've had the same reports, so far as I know without the ck patches, and also
in artsd....

I am seeing this with the fglrx (commercial ATI) driver version 8.20.8.

Ftr, I get the same stackdump when shutting down X. But look no

even tested last week before install. :)
