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- xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed- xenial'.
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.

From the commit message: This is a test of the ISA 3.0 "copy" instruction. That instruction has an L field, which if set to 1 specifies that "the instruction identifies the beginning of a move group" (pp 858). That's also referred to as "copy first" vs "copy". In ISA 3.0B the copy instruction does not have an L field, and the corresponding bit in the instruction must be set to 1. This test is generating a "copy" instruction, not a "copy first", and so on Power9 (which implements 3.0B), this results in an illegal instruction. So just drop the test entirely. We still have copy_first_unaligned to test the "copy first" behaviour. == Fix == * 83039f22 (selftests/powerpc: Remove Power9 copy_unaligned test) Patch can be cherry-picked into C, for Bionic it needs patches for bug 1828935 to land first (8d191587) to make it a clean cherry-pick. It's already landed in D and onward. == Test == Tested on a Power9 server with Cosmic, the broken tests will be removed correctly. == Regression Potential == Low. Code change limited to testing tools and just removing broken tests. We still have copy_first_unaligned to test the "copy first" behaviour. == Original Bug Report == This issue was only spotted on Power9 system "balter", for Power8 system, it has passed (skipped, and marked as passed) with this test: TAP version 13 selftests: copy_unaligned ======================================== test: test_copy_unaligned tags: git_version:unknown !! child died by signal 4 failure: test_copy_unaligned not ok 1..1 selftests: copy_unaligned [FAIL] selftests: copy_first_unaligned ======================================== test: test_copy_first_unaligned tags: git_version:unknown success: test_copy_first_unaligned ok 1..2 selftests: copy_first_unaligned [PASS] selftests: paste_unaligned ======================================== test: test_paste_unaligned tags: git_version:unknown !! child died by signal 4 failure: test_paste_unaligned not ok 1..3 selftests: paste_unaligned [FAIL] selftests: paste_last_unaligned ======================================== test: test_paste_last_unaligned tags: git_version:unknown !! child died by signal 4 failure: test_paste_last_unaligned not ok 1..4 selftests: paste_last_unaligned [FAIL] ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: linux-image-4.15.0-43-generic 4.15.0-43.46 ProcVersionSignature: Ubuntu 4.15.0-43.46-generic 4.15.18 Uname: Linux 4.15.0-43-generic ppc64le AlsaDevices: total 0 crw-rw---- 1 root audio 116, 1 Jan 24 06:50 seq crw-rw---- 1 root audio 116, 33 Jan 24 06:50 timer AplayDevices: Error: [Errno 2] No such file or directory: 'aplay': 'aplay' ApportVersion: 2.20.9-0ubuntu7.5 Architecture: ppc64el ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord': 'arecord' AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: Date: Thu Jan 24 07:05:20 2019 IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig': 'iwconfig' Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 0451:80ff Texas Instruments, Inc.
