[Bug 1716491] Re: New PMU fixes for marked events.

[Kleber Sacilotto de Souza]

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

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 1716491] Re: New PMU fixes for marked events.

[Joseph Salisbury]

I built a Zesty test kernel with a pick of commits
101dd590a7fa(4.13-rc3) and 09539f9(4.13-rc4).  The test kernel can be
downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1716491/

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

Thanks in advance!
