11.04 won't restart or shutdown

[fidamehran]

This CIFS issue is back with a vengeance on Natty! I run Mint 11, which is based on Natty. With past Ubuntu versions, having a CIFS network share connected via wireless when shutting down or restarting the computer would hang the shutdown for a minute or two - annoying, but livable (sort of). However, with Natty, the shutdown hangs indefinitely, forcing use of the power button. I tried all the workarounds listed in that link you mentioned to no avail. Finally, as a last-ditch effort, I added a line early in my /etc/init.d/umountnfs.sh file to explicitly unmount my network share, as follows:

do_stop () {
	# Write a reboot record to /var/log/wtmp before unmounting
	halt -w

	# Remove bootclean flag files (precaution against symlink attacks)
	rm -f /tmp/.clean /var/lock/.clean /var/run/.clean

	#
	# Make list of points to unmount in reverse order of their creation
	#

	exec 9<&0 </etc/mtab

umount //192.168.1.100/MyNET\ Shares/

	DIRS=""
...

The result? Nearly instantaneous shutdowns now!

I found, through insertion of logger and echo statements throughout umountnfs.sh, that during shutdown through the Gnome GUI, the script never finishes executing. It hangs somewhere shortly after evaluating /etc/mtab. Seems like the SMB/CIFS situation in Ubuntu is getting worse and worse...

How do you do that? I can't edit my umountnfs.sh file.
Tell me how, then tell me One more thing, do I add all the text you gave here (in the box)? And where do I add it in the file?

Sorry for disturbing people on a SOLVED thread. But my problem is nowhere near solving....

Hi,

I'm running Ubuntu 11.04 amd64 on a Dell Optiplex 990, which had the same problem and none of the solutions above worked for me. I found a solution in bug report in launchpad

Just add the option "reboot=pci" to GRUB_CMDLINE_LINUX in /etc/default/grub
to do this

sudo gedit /etc/default/grub

look for

GRUB_CMDLINE_LINUX=""

and change it to

GRUB_CMDLINE_LINUX="reboot=pci"

save, exit and update grub

sudo update-grub

Sorry for being bothering a solved thread.
Best regards.

I have Ubuntu studio 11.04 and it gets stuck at the very end of the shutdown process and I have to manually push the power button and it goes right off I don't have to hold it. What is strange is that it will restart just fine without any manual help. Other than that the OS works just fine.

Doesn't work for me. I am not sure why this thread is marrked as SOLVED but the problem still remains (at least for me). I can shutdown fine but not restart. When I restart, it hangs while shutting down.

Nice, I have been looking for this answer for a while. I have the exact machine except with and i5 64 bit cpu and this fixed my problem.
