  == SRU Justification ==
  IBM unrecovered MCE and HMI errors are sent through a special restart OPAL
  call to log the platform error. The downside is that they don't go
  through normal Linux crash paths, so they don't give much information
  to the Linux console.

  IBM is requesting to have the commit b746e3e01e70d23ef53dcde1203ab78a1b7ac514
  in the Zesty kernel.

  Commit b746e3e01e70d2 is in mainline as of 4.14-rc1.

[Kernel-packages] [Bug 1735159] Re: powerpc/powernv: Flush console before platform error reboot

[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!

Bug description:
  == SRU Justification ==
  IBM unrecovered MCE and HMI errors are sent through a special restart OPAL
  call to log the platform error. The downside is that they don't go
  through normal Linux crash paths, so they don't give much information
  to the Linux console.

  IBM is requesting to have the commit b746e3e01e70d23ef53dcde1203ab78a1b7ac514
  in the Zesty kernel.

  Commit b746e3e01e70d2 is in mainline as of 4.14-rc1.

  Breno Leitao from IBM did a backport of this commit.

  powerpc/powernv: Flush console before platform error reboot

  == Regression Potential ==

reporter.
  The bug reporter states the test kernel resolved the bug.

[Manoj Iyer]

Since 4.10 was replaced with 4.13 kernel version for linux-hwe, would it
make sense to backport this patch to 4.13 (Artful) ? Could you
(jsalisbury) please add Artful as a target series to track?

Joseph,

I tested this kernel and it works fine without any seen regression.
Thanks for the kernel:

[Joseph Salisbury]

I built a Zesty test kernel with your back port.  The test kernel can be 
downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1735159/

Can you test this kernel and see if it resolves this bug?
