[Kernel-packages] [Bug 1739498] Comment bridged from LTC Bugzilla
--- Comment From frede...@fr.ibm.com 2018-03-23 12:29 EDT---
Hi,
I got my hands on a WS system and could boot kernel 4.13.0-38.43 with
disable_radix kernel option
and I confirm that this issue does not appear anymore.
(I checked before that I actually got it with 4.13.0-37.42)
Regards,
F.

== SRU Justification ==
IBM is seeing a crash on Power9 when running on Artful.
This issue happens only when disabling RPT ("disable_radix"), which is not
the default in Artful.
These fixes are already in Bionic master-next, so they are only being
requested
in Artful.

These commits are specific to powerpc and fix a crash.
== Test Case ==
A test kernel was built with these patches and tested by the original bug
reporter.
The bug reporter states the test kernel resolved the bug.

Hi smb/Canonical,
could we extend the validation period ? : I couldn't find a WitherSpoon system
so far to test this.
Let me know, thanks

Hi,
Aneesh, right, I missed the 2 other ones. I rebuilt a kernel with the 3
patches, thanks for having thought of this, because that fixes the issue. Some
details now :
actually this issue happens only when disabling RPT ("disable_radix") which is
not the default in Artful.
Also I could have it on Witherspoon systems but not on Boston (having an other
issue, which may hide this one... FYI the kernel loops infinitly displaying :
