[regression 13.10] Can't reboot (but can shut down)

[Rebecca Palmer]

Since upgrading to 13.10, attempting to restart (with either "shutdown -r now" or the system menu item) hangs with a "reboot: restarting system" message instead of actually rebooting, but shutting down still turns the system off.

WORKAROUND: adding reboot=p to the kernel command line (https://wiki.ubuntu.com/Kernel/KernelBootParameters) avoids this bug.

The reboot(8) man page says to file bugs against upstart; should that be changed?

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.12 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Rebecca Palmer (rebecca-palmer)]

I'm not comfortable with downloading a kernel from an insecure site (why isn't kernel-ppa a real PPA, where it would have https and signatures?), so I tested the upstream git head instead (https://wiki.ubuntu.com/KernelTeam/GitKernelBuild); it also had this bug.

[Rebecca Palmer (rebecca-palmer)]

Kernel 3.8.0-32 (the next newest on my boot menu, probably the Raring kernel) does not have this bug.

[Rebecca Palmer (rebecca-palmer)]

Both 3.8 and 3.11 work with reboot=p (https://wiki.ubuntu.com/BIOSandUbuntu#Reboot_Methods); 3.8 doesn't work with any other reboot=, which suggests the regression is caused by a change of default.

[James Hunt (jamesodhunt)]

@Rebecca: yes, but the man page is referring to bugs in the reboot command. That commands calls the reboot system call and that is where the problem lies (in the kernel).

[penalvch (penalvch)]

Rebecca Palmer, as per http://www.dell.com/support/drivers/us/en/19/Product/latitude-e6520 an update is available for your BIOS (A18). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Thank you for your understanding.

[Rebecca Palmer (rebecca-palmer)]

Closing the bug as I prefer not to risk bricking my system to fix something that has an easy workaround (and rumour suggests the FreeDOS method no longer works with recent Dell BIOS updates: http://askubuntu.com/questions/100945/how-do-i-update-the-bios-of-a-dell-laptop/237742#237742).
