== SRU Justification ==
A regression was introduced by commit 8c069ff4bd606 in v3.14-rc1. IBM
is requested commit 4bbaf2584b86 in all Ubuntu kernels to resolve this
isue.
Bug Description: cpum_sf: ensure sample freq is non-zero
Symptom: A kernel crash might occur.
Problem: An FP divide exception during the sample rate
initialization for the hardware sampling facility.
Solution: Ensure that the sample frequency of the perf
event attribute is non-zero.
== Fix ==
4bbaf2584b86 ("s390/cpum_sf: ensure sample frequency of perf event attributes

== Regression Potential ==
Low. Fix is specific to s390.
== 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.

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-
bionic' to 'verification-done-bionic'. If the problem still exists,
change the tag 'verification-needed-bionic' to 'verification-failed-
bionic'.
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.

[Kernel-packages] [Bug 1772593] Re: cpum_sf: ensure sample freq is non-zero
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!

[Kernel-packages] [Bug 1772593] Re: cpum_sf: ensure sample freq is non-zero
I built Xenial, Artful and Bionic test kernels with commit 4bbaf2584b86b0772413edeac22ff448f36351b1. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1772593 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.
