---Debugger---
A debugger is not configured
---Steps to Reproduce---
1. Log into P9 Ubuntu 18.04 host, take console of guest `srikanth_
2. Run TM selftests
git clone --depth 1 https:/
We will observe one of the tm tests failing, mentioned below:
selftests: tm-trap
=======
test: tm_trap_test
tags: git_version:c18bb39
Little-Endian machine detected. Checking if endianness flips inadvertently on trap in TM... yes!
failure: tm_trap_test
not ok 1..11 selftests: tm-trap [FAIL]
Expected result: All tm selftests should have been pass on the P8 compat guest.. giventhat we had TM workaround patches in latest Ubuntu BIONIC host kernel
Stack trace output:
no
Oops output:
no
