This is what I get in that case on the console (screenshotted, OCRed and corrected): 2c0 Stopped in pid 0.216 (system) at netbsd: breakpoint+0x5: leave breakpoint() at netbsd:breakpoint+0x5 upanic() at netbsd: upanic+0x171 panic() at netbsd:panic+0x3c usbd_transfer() at netbsd:usbd_transfer+0x5be usbd_do_request_len() at netbsd:usbd_do_request_len+0xdf usbd_do_request() at netbsd:usbd_do_request+0x21 usbd_set_report() at netbsd:usbd_set_report+0x76 ukbd_set_leds_task() at netbsd:ukbd_set_leds_task+0x5d usb_task_thread() at netbsd:usb_task_thread+0xb5 ds 0 es 0 fs 180 gs 5d80 rdi 0 rsi ffffffff81da8000 rbp ffffb4893f1d5dd0 rbx ffffffff813d3363 ostype+0x21613 rdx 1 rcx ffffffffffffff rax 800000000000000 r8 0 r9 0 --db_more-- As there is no working keyboard, there isn't much I can do to get more information at that point.
