The coprocessor's state kept the moment its fast path stops, and a recovery that waits for the new boot, 2026-10-31

819: on 2026-10-31 the first XGS 3300 (vendor version 23) was cold-started after a night switched off, and 182 s into its coprocessor's boot the coprocessor's console printed one line - Unable to handle kernel NULL pointer dereference at virtual address 00000001 - and nothing after it. The heartbeat was taken as stopped 30 s later and the recovery took the coprocessor up again in place, about three minutes from the oops to an answering heartbeat. Which function failed is not known: the trace never reached the console, and after the reset the coprocessor's pstore held no record of it - its kernel never finished the oops.
