Re: ❌ FAIL: Test report for kernel 5.5.7-60528b7.cki (stable-queue)

----- Original Message -----

Hello,

We ran automated tests on a recent commit from this kernel tree:

   Kernel repo:
   https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git
        Commit: 60528b79e30a - kvm: nVMX: VMWRITE checks unsupported
        field before read-only field

The results of these automated tests are provided below.

Overall result: FAILED (see details below)
         Merge: OK
       Compile: OK
         Tests: FAILED

All kernel binaries, config files, and logs are available for download here:

https://cki-artifacts.s3.us-east-2.amazonaws.com/index.html?prefix=datawareh...

One or more kernel tests failed:

s390x:
 ❌ LTP

All instances of similar panics [1] manifest mostly on s390 and at first glance look like memory corruptions.

I'm looking to confirm, whether this has been fixed by:

commit 6fcca0fa48118e6d63733eb4644c6cd880c15b8f Author: Suren Baghdasaryan surenb@google.com Date: Mon Feb 3 13:22:16 2020 -0800
