When I booted into my 6.4-rc1 (but also rc2) kernel on my
Pine64 Quartz64 Model A, I noticed a crash which seems the same as
above, but I didn't have such a crash with my 6.3 kernel.
Searching for 'hantro' led me to this commit as the most likely culprit
but when I build a new 6.4-rcX kernel with this commit reverted,
I still had this crash.
Do you have suggestions which commit would then be the likely culprit?
Cheers,
Diederik
For completeness, this is the error I got with 6.4-rcX:
