Probing as running through three times (but there's a lot more PCIe cards ther, I didn't say the card being detectede). ^T would not work at this point. I could break into the debugger thoug, did so and typed cont waiting a bit longer and upon trying to get into debugger again this happened: KDB: enter: Break to debugger timeout stopping cpus [ thread pid 9 tid 100240 ] Stopped at kdb_alt_break_internal+0x180: str xzr, [x19, #1408] db> timeout stopping cpus panic: Assertion pcb->pcb_fpusaved == NULL failed at /usr/src/sys/arm64/arm64/vfp.c:209 cpuid = 0 time = 1712167778 KDB: stack backtrace: db_trace_self() at db_trace_self db_trace_self_wrapper() at db_trace_self_wrapper+0x38 vpanic() at vpanic+0x1a4 panic() at panic+0x48 vfp_save_state_savectx() at vfp_save_state_savectx+0x48 savectx() at savectx+0x38 arm_gic_v3_intr() at arm_gic_v3_intr+0xe4 intr_irq_handler() at intr_irq_handler+0x88 handle_el1h_irq() at handle_el1h_irq+0x14 --- interrupt lock_delay() at lock_delay+0x18 __mtx_lock_sleep() at __mtx_lock_sleep+0xdc __mtx_lock_flags() at __mtx_lock_flags+0x138 softclock_call_cc() at softclock_call_cc+0xd0 softclock_thread() at softclock_thread+0xb8 fork_exit() at fork_exit+0x78 fork_trampoline() at fork_trampoline+0x18 Uptime: 16m57s Automatic reboot in 15 seconds - press a key on the console to abort -- Bjoern A.
