The issue seems to stem from reading /proc/net/rtl8822ce/<interface>/sec_cam. This read takes about 40s before printing seemingly null data, and the io lockup causes issues with the realtime kernel. I'm not exactly sure why it's causing a null pointer deref and rt_mutex backtrace though. The rtl8822ce driver is definitely hitting timeouts when trying to read the sec_cam registers, but that seems like something the mutexes should handle gracefully.
