I built a Zesty test kernel with a pick of commit ea9a26d117c. The test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1694485/

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

Sudeesh, Vaibhav,

Canonical is waiting on you testing the kernel provided above.

Tried testing given kernel (linux-image-4.10.0-26-generic_4.10.0-26.30~lp1694485_ppc64el.deb). Unfortunately still I'm hitting the issue mentioned in #12(BZ156746 and BZ154870) . That fix has gone into 4.10-30 kernel. It would require a new kernel rebuilt with both the fixes to validate this issue.

[Joseph Salisbury (jsalisbury)]

I built a 4.10.0-40 based test kernel with a pick of commit:
ea9a26d cxl: Force context lock during EEH flow

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1694485/

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

The reported issue is no more seen with the given kernel.

[Manoj Iyer (manjo)]

Since 4.10 kernel was replaced with 4.13 linux-hwe, would it make sense to resubmit these patches for 4.13 (Artful)? Would you (jsalisbury) be able to add a target series for Artful for tracking?
