Marking verification done, though I've not had explicit testing results from Amazon. Their comment in SF:#00308561 was, "thanks for putting in the extra effort to get this released so quickly." By that I assume they have been successfully using the test kernel as this bug was an arm64 show stopper for them. ** Tags removed: verification-needed-bionic verification-needed-focal verification-needed-groovy verification-needed-hirsute ** Tags added: verification-done-bionic verification-done-focal verification-done-groovy verification-done-hirsute -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1926184 Title: locking/qrwlock: Fix ordering in queued_write_lock_slowpath() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1926184/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1926184] Re: locking/qrwlock: Fix ordering in queued_write_lock_slowpath()
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- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'. 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.
