BTW, are you sure the first problematic kernel is 5.12?
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.
BTW that may be an interesting thing to try: Can you boot with "megaraid_sas.host_tagset_enable = 0" kernel option and see whether the issue reproduces?
Yep. -- Chris Murphy
