The KernelCI bisection bot found that commit db6f68b51e5c ("media:
verisilicon: Do not set context src/dst formats in reset functions")
is triggering problems at boot on rk3399-gru-kevin - there are oopses
printed early on in userspace initialisation while enumerating the v4l
devices. The top of the backtrace is:

which does seem relevant.
I've left the full report below, including more details like links to
