2018-03-19 Thread Stefan Bader 
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
artful' to 'verification-done-artful'. If the problem still exists,
change the tag 'verification-needed-artful' to 'verification-failed-
artful'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Xenial does not have 83e3c48729d9ebb7af5a31a504f3fd6aff0348c4. Though,
linux-hwe 4.13 has been shipped for Xenial. So, on the kernel side,
there is nothing to fix on our 4.4 kernels, but on the makedumpfile
side, that still needs to be fixed if we want to have some of those
kernels dumpable.

  makedumpfile will fail to dump in that case. Backporting a kernel fix
  will make it work again, but that means that some kernel versions
  won't be dumpable. A solution for makedumpfile should be done as well.

2018-02-16 Thread Thadeu Lima de Souza Cascardo 
I intend to send this fix upstream and test it with more kernel
versions. At least added with a 4.13 kernel without the patch and one
with the patch.
