LIRC causes hard kernel freezes every ~26 hours

[Stephan Sokolow]

After installing LIRC for my Streamzap IR remote, I began to experience a hard kernel freeze (no blinking keyboard LEDs and kdump wouldn't trigger) roughly every 24 to 26 hours. Removing LIRC restored system stability.

LIrc, being a userspace program, cannot cause a kernel freeze. This bug should be re-assigned to the kernel

[Alec Leamas (leamas-alec)]

That said, lirc might of course trigger a kernel bug. What's the content of your hardware.conf (when the bug occurred). In particular, does it load any kernel modules?
