Hi, in /boot/device.hints I have: hint.uart.1.flags=0x10 and till about a week old kernel, I get the serial console ok. with today?s update, this is broken: the boot output stops after showing: ... cpu15 (AP): APIC ID: 7 ioapic1: Changing APIC ID to 1 ioapic0 <Version 2.0> irqs 0-23 on motherboard ioapic1 <Version 2.0> irqs 32-55 on motherboard Freebsd/amd64 (rnd) (ttyu1) Login: and later, escape to debugger failes - i.e hitting \n~^B gets me nowhere. from dmesg: ? ioapic1: Changing APIC ID to 1 ioapic0 <Version 2.0> irqs 0-23 on motherboard ioapic1 <Version 2.0> irqs 32-55 on motherboard kbd1 at kbdmux0 acpi0: <DELL PE_SC3> on motherboard ? so what is broken in kbdmux? thanks, danny
