Public bug reported:
sometimes when I boot my wireless connection isn't working. I try to
open an Terminal but my zsh isn't responding. Even if I try to change to
tty1 I can't do anything. I can still open gnome-system-monitor, but I
can't kill any "hanging" application. "WAITING CHANNEL:
work_flush_queue" I can't even restart or shutdown! In kern.log and
syslog I found this:
