Hi, I occasionally see the below trace with Linus' master on an

That bisection led to this commit:

drm/ast: Add detect function support
<snip>
I confirmed that if I revert it from v5.15-rc4 (after reverting
its dependent 572994bf18ff "drm/ast: Zero is missing in detect
function"), the problem goes away.
Full .config, dmesg attached.
I can test any possible fixes...
Ping - if no fixes are in the works, can the offending commit(s)
be reverted?
Thanks,
Kim
