| |
I just got a few "BUG: spinlock lockup" messages while trying to reboot my box (shutdown -r now).
Unfortunately all I had available to capture the situation was a crappy camera phone, so all I have are some bad quality jpeg images. I've put the images up here: ftp://ftp.kernel.org/pub/linux/kernel/people/juhl/images/screenshot0.jpg ftp://ftp.kernel.org/pub/linux/kernel/people/juhl/images/screenshot1.jpg ftp://ftp.kernel.org/pub/linux/kernel/people/juhl/images/screenshot2.jpg
The kernel I was running was one generated during a "git bisect" session, but unfortunately I no longer know exactely where in the session it was from. All I know is that it is somewhere between 2.6.18 and 2.6.19-rc1.
It happened shortly after I did a alt+sysrq+t (which I did since I was wondering why it was taking ages to unmount my local filesystems) - these BUG messages showed up roughly 4 or 5 seconds after that.
I've tried to reproduce it, but without luck.
I'm just hoping that someone can spot something obvious from the messages. I don't have a clue on this one.
