Title: arm64 kvm-unit-tests timer test failing on 18.04 Status in linux package in Ubuntu: Triaged Status in linux source package in Bionic: Triaged Bug description: kvm-unit-tests performs 12 timer tests in the latest version, one of them failing with the latest Ubuntu LTS kernel. This issue has been fixed in mainline commits 7afc4ddbf299a13aaf28406783d141a34c6b4f5a and 245715cbe83ca934af5d20e078fd85175c62995e (part of 4.19.0 release), which are tagged with "Cc: Stable # 4.15+" and "Fixes: ...". Could you please backport them to your tree? "patch" applies them with some fuzz only (no additional fixing needed). Here is what I did: - Boot 4.15.0-38-generic on an ARM Juno r1 board (but every arm64 h/w would do). - Run kvm-unit-tests: $ git clone git://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git $ cd kvm-unit-tests $ ./configure && make $ ./run_tests.sh This will mark the timer test as failed: FAIL timer (12 tests, 1 unexpected failures) A more detailed log can be get by: $ arm/run arm/timer.flat I then fetched the official Ubuntu kernel (apt-get source), applied the two patches mentioned above and rebuilt the kernel (with the .config from /boot). This will report the timer as pass: PASS timer (12 tests) So could you please backport those two patches to make kvm-unit-tests (and its users) happy? Btw: I was wondering whether you have some process to find those stable fixes, even with the 4.15 base kernel being EOL for quite a while now. Please bear with me if you do and I was just too impatient ;-) Thanks!
