100%

It consistently reproduces with any 5.12 series kernel, including from c03c21ba6f4e which is before rc1. It's frustrating that git bisect produces kernels that won't boot, I was more than half way through! :D And could have been done by now...

We've been running on 5.11 series kernels for a year because of this problem.
