Hi,

just in case someone finds it helpful:

SError Interrupt on CPU3, code 0x00000000bf000002 -- SError
CPU: 3 UID: 0 PID: 40083 Comm: devmem Not tainted 6.15+ PREEMPT
pstate: 60000000 (nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=3D--)
Kernel panic - not syncing: Asynchronous SError Interrupt

What did i do? Wrote 32-bit value to an ISP register (0x32E22E2E4C =3D
a histogram-64 register) while repeatedly reading other ISP
registers (in userspace). The video stream was active.

This ISP apparently has its own problems.
