Hi, Some time ago I have reported that when scroll lock is pressed during boot on amd64 box panic occurs (it has to be pressed somwhere after sc0/vga0 kernel message during boot.Also if I use serial console this can't be repeated. Btw if in /boot/device.hints hint.kbdmux.0.disabled is set to 1 this doesn't happen. But, today even after panic for some reason I could type so here is what I've got from ddb: Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0xffffffff000000b1 fault code = supervisor read, page not present instruction pointer = 0x8:0xffffffff8065b026 stack pointer = 0x10:0xffffffff80b3c790 frame pointer = 0x10:0xffffffff80b3c7c0 code segment = base 0x0, limit 0xffffff, type 0x1b = DPL 0, pres 1, long 1, def 32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 0 (swapper) [thread pid 0 tid 0 ] Stopped at sc_cnputc+0x96: testb $0x2,0xb1(%rbx) db> bt Tracing pid 0 tid 0 td 0xfffffffff80935c80 sc_cnputc() at sc_cnputc+0x96 putchar() at putchar+0xc8 kvprintf() at printf+0xe7 device_printf() at device_printf+0x6f ad_attach() at ad_attach+0x298 device_attach() at device_attach+0x292 bus_generic_attach() at bus_generic_attach+0x18 ata_identify() at ata_identify+0xea ata_boot_attach() at ata_boot_attach+0x50 run_interrput_driven_config_books() at run_interrypt_driven_config_books+0x78 mi_startup() at mi_startup+0xd3 btext() at btext+0x2c db> However I couldn't call doadump() since there is no device defined to dump to.
