Hi Jason,

as I understand you've tried to do bisect, can you instead try building 
kernels checking out following tags:
v6.1      v6.1.1    v6.1.2    v6.1.3    v6.1.4    v6.1.5    v6.1.6 
v6.1.7    v6.1.8
and report when it stops working, so it narrows scope of what we look 
at? I assume that kernel builds are done using upstream stable kernel 
(from https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/).

Thanks,
Amadeusz
