set_task_cpu+0x240/0x250
This is a regression and was introduced by the following two commits in
v4.15-rc1:
01eaac2b0591 ("powerpc/mce: Hookup ierror (instruction) UE errors")
ba41e1e1ccb9 ("powerpc/mce: Hookup derror (load/store) UE errors")
This regression is fixed by commit 75ecfb49516c in v4.17-rc3. The
commit was also cc'd to upstream stable, but it is being SRU'd to get
the fix into Ubuntu without waiting for it to come down via stable
updates.
== Fix ==
75ecfb49516c ("powerpc/mce: Fix a bug where mce loops on memory UE.")
== Regression Potential ==
Low. Limited to powerpc. The commit was also cc'd to upstream stable
so it will recieve additional upstream stable review.
== Test Case ==
A test kernel was built with this patch and tested by the original bug
reporter.
The bug reporter states the test kernel resolved the bug.

== SRU Justification ==
IBM reports seeing the following during their testing:
WARNING: CPU: 97 PID: 11965 at
/build/linux-0zaMZw/linux-4.15.0/kernel/sched/core.c:1189
set_task_cpu+0x240/0x250
This is a regression and was introduced by the following two commits in
v4.15-rc1:
01eaac2b0591 ("powerpc/mce: Hookup ierror (instruction) UE errors")
ba41e1e1ccb9 ("powerpc/mce: Hookup derror (load/store) UE errors")
This regression is fixed by commit 75ecfb49516c in v4.17-rc3. The
commit was also cc'd to upstream stable, but it is being SRU'd to get
the fix into Ubuntu without waiting for it to come down via stable
updates.
== Fix ==
75ecfb49516c ("powerpc/mce: Fix a bug where mce loops on memory UE.")
== Regression Potential ==
Low. Limited to powerpc. The commit was also cc'd to upstream stable
so it will recieve additional upstream stable review.
== Test Case ==
A test kernel was built with this patch and tested by the original bug
reporter.
The bug reporter states the test kernel resolved the bug.

I built a test kernel with commit 75ecfb49516c53. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1774964 Can you test this kernel and see if it resolves this bug? Note about installing test kernels: • If the test kernel is prior to 4.15(Bionic) you need to install the linux-image and linux-image-extra .deb packages. • If the test kernel is 4.15(Bionic) or newer, you need to install the linux-modules, linux-modules-extra and linux-image-unsigned .deb packages.
