System : OpenBSD 4.9
Details : OpenBSD 4.9-current (GENERIC) #4: Sun Apr 10 21:15:38 MDT
2011
[email protected]:/usr/src/sys/arch/sparc64/compile/GENERIC
Architecture: OpenBSD.sparc64
Machine : sparc64
>Description:
Kernel panics when keyboard and display are connected. Booting
with serial cable works fine. Also OpenBSD 4.2 works with display
and keyboard that was previously installed.
This happens right after uhub0 has attached.

>How-To-Repeat:
Boot with display and USB keyboard attached.
>Fix:
Workaround currently is to boot without keyboard so the machine
uses serial line instead.

console is /pci@1f,0/isa@7/serial@0,3f8
