[Kernel-packages] [Bug 1706033] Re: [P9, Power NV][ WSP][Ubuntu 16.04.03] : perf hw breakpoint command results in call traces and system goes for reboot.

[Po-Hsu Lin]

Hi chavez,

As the system mentioned in the bug report was running on the 4.10 kernel
(Zesty kernel), that's why it was requested to do the verification
request for Zesty.

In your case, I think it's ok to verify this with the updated 4.10
kernel for Xenial, aka the Zesty-HWE kernel (4.10.0-38.42~16.04.1).

Thanks

[Kernel-packages] [Bug 1706033] Re: [P9, Power NV][ WSP][Ubuntu 16.04.03] : perf hw breakpoint command results in call traces and system goes for reboot.

[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!

[Kernel-packages] [Bug 1706033] Re: [P9, Power NV][ WSP][Ubuntu 16.04.03] : perf hw breakpoint command results in call traces and system goes for reboot.

[Joseph Salisbury]

I built a Xenial test kernel with commit d89ba5353f301971dd7.  The test
kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1706033/

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

Thanks in advance!
