Timeout opening/writing control channel /dev/initctl
From FVue
Problem
In the process list ps -ef I can see a lot of `defunct' processes:
joe 14346 1 0 02:06 ? 00:00:00 [ssh] <defunct> root 14414 1 0 02:12 ? 00:00:00 [cdrecord] <defunct> joe 14662 1 0 05:00 ? 00:00:00 [zcat] <defunct>
When I try to give the command shutdown -r now I get these error messages:
shutdown: timeout opening/writing control channel /dev/initctl init: timeout opening/writing control channel /dev/initctl
All I can remember I mounted an USB mp3 player with mount /dev/sda /mnt/iaudio and unmounted it with umount /mnt/iaudio. In fact, physical terminal tty hangs with these lines:
sd 3:0:0:0: Attached scsi removable disk sda usb 1-1: USB disconnect, address 5
I also did an sudo apt-get upgrade
Environment
- Debian 4.0
Solution
The problem seems to have been instigated by an apt-get update. To reboot, give the command:
sudo reboot -f

- Same problem in blog with
reboot -fanswer
But if I call reboot -f `shutdown' isn't going to be called, so there must be a better solution?
From info init: "Usage of SIGPWR and /etc/powerstatus is
discouraged. Someone wanting to interact with init should use the
/dev/initctl control channel - see the source code of the sysvinit package
for more documentation about this."
- Linux From Scratch HOWTO: Installing Sysvinit
- Chapter 4 handles installing Sysvinit and shows this script:
@if [! -p $(ROOT)/dev/initctl ]; then \ echo "Creating $(ROOT)/dev/initctl" \ rm -f $(ROOT)/dev/initctl; \ mknod -m 600 $(ROOT)/dev/initctl p; fi
Checking if /dev/initctl exists:
$> ls -l /dev/initctl prw------- 1 root root 0 2008-01-09 22:41 /dev/initctl $>

- More info on /dev/initctl
Tried this:
mv /dev/initctl /dev/initctl_ mknod -m 600 /dev/initctl p
but shutdown still won't work.
From /var/log/auth.log I can see the timestamp from /dev/initctl is the same as when I gave the commands sudo apt-get upgrade and sudo apt-get update
Looking at /var/log/dpkg.log shows the upgrade started at 2008-01-09 22:41 - the last modified time of /dev/initctl, but the log shows no errors. Below is an grep upgrade dpgk.log
