^ mouthful of a topic.
Debian Lenny with a smattering of packages from Sid, 2.6.22-2-686 kernel, on a Thinkpad R61.
The story is, hibernation works on my laptop, except when it doesn't:
Code:
Sep 7 12:45:56 thrawn kernel: Stopping user space processes timed out after 20 seconds (1 tasks refusing to freeze):
Sep 7 12:45:56 thrawn kernel: wpa_supplicant
That's the first time. The next time I try to hibernate,
ip and
NetworkManager also refuse to freeze. So I try to kill the processes, but now every
sudo command is freezing doing nothing and not responding to ^C, ^D, or ^Z. And if I try to hibernate again, now
sudo won't freeze. So I kill X (Ctrl+Alt+Bksp woohoo) and log in on a TTY. Same story, so I go to the next TTY (can't interrupt the command I tried, as before) and log in as root.
kill -9 XYZ runs and exits silently but does not kill the offending processes.
poweroff (still as root) starts to work but then freezes on a stopping a network-related program (Shorewall in this case). Fortunatly, the magic SysRq key combo works, so I Alt+SysRq+(R, E, I, S, U, B) my way to an emergency reboot.
But this is obviously not ideal, and I also have no idea how a process can not be killed by root
kill -9ing it.
Ideas? Help? Need more details?
