Public bug reported:
After an upgrade to raring, I've experienced a bug where firefox and X
are each consuming a CPU doing nothing useful. When this happens, I can
still log into the machine remotely with no problems, but the console is
completely frozen. The X cursor doesn't move, unity doesn't respond,
windows are not refreshing, and I can't even change VTs (from the
keyboard, or over ssh - if I run 'sudo chvt 1', it hangs).
It appears that X and firefox are both busy, but strace of firefox shows
no output. kill -9 of the firefox process also has no effect (bug
#117499). There is nothing logged in dmesg or in the X log that seems
relevant.
After debugging this for about an hour, the firefox process spontaneously died,
at which point X also stopped monopolizing the CPU; but the console was still
frozen, A few minutes later, the VT switch request seems to have registered
and I wound up on VT1. However, switching back to VT7 does not result in the
screen being refreshed, and 'sudo chvt 1' again hangs.
