Does userland print anything relevant? Can you compare "clinfo" output between
Mesa versions? Can you confirm the regression on -CURRENT?

Mesa upstream is poorly tested on old kernels drivers. Stable Linux distros
have old Mesa + old kernel but on FreeBSD packages are rolling while GPU kernel
drivers are frozen except on -CURRENT. Also, Mesa ports are currently split in
a way which is error-prone.
