This was reproduced with the linux-generic kernels. The generic kernels that experience this behavior are: 5.0.0-31-generic and 5.3.0-16-generic.
This behavior was corrected when the following upstream commits were added to the lttng-modules package in Bionic: 2ca0c84f0b ("Fix: mm: create the new vm_fault_t type (v5.1)") d6cd2c9598 ("Fix: pipe: stop using ->can_merge (v5.1)") 1b7b9c650e ("Fix: Remove start and number from syscall_get_arguments() args (v5.1)") d88e2fe5c3 ("fix: timer/trace: Improve timer tracing (v5.2)") 36ac1139f0 ("fix: mm/vmscan: drop may_writepage and classzone_idx from direct reclaim begin template (v5.2)") a6a26911cc ("fix: random: only read from /dev/random after its pool has received 128 bits (v5.2)") ** Package changed: linux-azure (Ubuntu) => lttng-modules (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1846485 Title: lttng causes crash with 5.0 based kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lttng-modules/+bug/1846485/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
