5.10.0 is very old and obsolete and over 20 thousand patches old.
Please, if you are testing LTS kernels, use the latest one.

Do you have a proposed patch for this fix now that you have a way to
reproduce this?  Do you see this in real situations or only in

And can you reproduce this on 6.4-rc1?  Do you have a reproducer?
