Comment 8 for bug 1914976

As the 5.0 kernel is no longer supported, I'm afraid being able to reproduce the issue with that kernel will not allow a potential fix to be SRU'ed into the 5.4 kernel.

Could you confirm with your engineers that the patch Dann referred to in comment #3 would address the issue?

If it does address the issue, then in order to SRU this patch into the 5.4 kernel we would either need a reproducer for the 5.4 kernel, or for a Huawei engineer to submit it to the upstream stable kernel. The Ubuntu kernel regularly integrates patches from the upstream stable kernel. So, this approach would probably be simpler.

The following describes the upstream process to apply fixes to the upstream stable tree: https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.htm
