Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.2 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'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

Title:
  [Packard Bell EasyNote ENTF71BM] System will hang on reboot / poweroff

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Seems similar to
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1341925 and
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1346269

  System will hang at dw_dmac INTL9C60:00: invalid resource

  Adding the following to /etc/modprobe.d/blacklist.conf bypasses the issue and the laptop works without issue:
  blacklist dw_dmac
  blacklist dw_dmac_core

  Version: Ubuntu 3.19.0-15.15-generic 3.19.3
