[Bug 1372006] Re: pci_devices does not terminate at computer shutdown


ahau, could you please test the latest upstream kernel available from
the very top line at the top of the page (the release names are
irrelevant for testing, and please do not test the daily folder)
following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow
additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested exactly shown as:

This can be done by clicking on the yellow circle with a black pencil
icon next to the word Tags located at the bottom of the bug description.

If the mainline kernel does not fix this bug, please add the following tags:

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your

  pci_devices does not terminate at computer shutdown

Status in linux package in Ubuntu:

Bug description:
  Shutdown does not halt on my Dell Precision 390
  the shutdown sequence prints on the console:

  mount: / is busy

  /etc/init.d/sendsigs does not terminate systemd-udevd

  Only solution: enable and use ALT-SYSREQ REISUB (to keep the root fs

  I tried to change GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub  (+

  GRUB_CMDLINE_LINUX_DEFAULT="quiet nosplash reboot=pci"  or
  GRUB_CMDLINE_LINUX_DEFAULT="quiet nosplash reboot=bios" or
  GRUB_CMDLINE_LINUX_DEFAULT="quiet nosplash acpi=force

  Shutdown still hangs with 'mount: / is busy'
  I even updated the BIOS from 2.0.4 to 2.06, no luck.

  When booting from a Knoppix 6.0.1 CD with a 2.6 kernel,  shutdown
  works and halts the system to poweroff state.

  Any ideas?
