I don't know if this will help, but I'm having this problem on kernel 7.1-rc1.
I tried using git bisect to find the problematic commit, but it's 13 iterations
long and sometimes the kernel won't start, so I gave up. If you have a list of
suspicious commits, I could search for the problematic one this weekend if that
helps.
