Hello,
I'm experiencing weird system hangs with recent -mm. After a few hours of uptime for no obvious reason system hangs and is (almost) unusable until reset.
a few facts:
- this happens on random basis without anything obvious that could trigger it - if some music is played and system hangs the music starts looping in thight loop causing weird sound effects - sometimes I'm able to switch from X to console, it takes a few seconds to switch though - system is eating 100% CPU what is shown by my laptop fans - when I switch to console I can issue SysRq commands but they do not work i.e.: SysRq + P shows only the first line: "SysRq: Show Regs" - in console in which I can log into the system I'm unable to type - in console where syslog is logging *.* I'm able to type - if the wifi card was plugged into the system before the hang happend the networking seems to work ok - when I reattach my pcmcia wifi card it doesn't get detected (nothing happens) - when I try to login to my laptop from remote machine the line "login:" and that's it, nothing more happens - system logs show nothing interesting as even if there is some usable debug info I'm unable to SysRq + S and read it after reboot
With 2.6.20-mm1 it happened as well. I get the feeling that 2.6.20-rc2-mm1 needs a bit more uptime to hit this bug.
