Some library used by skype can freeze system

Ive had this happen quite a few times too (normally when making a call) but didnt know/wait long enough to see it come back.

System locks solid, including mouse cursor, like you say. Next time Ill wait.

just happened again, this time I waited and the system recovered - dunno if this is relevant, but this is what the kernel logged:

I get the same lock-up. It happens more or less randomly when I get called or when I call someone. (Sometimes it just works, though.)

When it happens, everything freezes: music player stops (though I'm not sure if immediately), mouse stops moving, numlock and capslock are frozen.

If I press ctrl+alt+backspace X _does_ restart. I can log-in normally and usually (I think) Skype works the second attempt. (Last time I got a crash report for Skype after restarting X, but for some reason I couldn't get it to send itself). I think ctrl+alt+del can restart the whole system. I'm not sure, but I think once I managed to get to a console while X was frozen. I'll try again it next time it freezes.

Sometime the machine unfreezes itself after a while, with no message of any kind. Skype works after that normally (as far as I can tell).

Don't hesitate to ask if there is anything I can check.

Last time it happened I used ctrl+alt+backspace to restart X and log in. (Skype worked afterwards.) I'm not sure if the messages are from restarting X or from the freeze:

This is the tail of /var/log/messages for the last time it froze:

Same as first post - still happens.

Still looks like no dev. has seen the bug / wanted to make it confirmed at least - please look into it.

Sorry - now I've found it, but in 2.6.15
https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.15/+bug/53216
Can anyone do a merge under general kernel source, or any other proper place? Still happens in 2.6.17

I suggest marking this as duplicate of #53216 and join forces over there to fix this problem.
