>Organization:
	Wasabi Systems
>Environment:
	Asus & Dell x86 systems (AMD Athlon & Intel P-something) / NetBSD
>Description:
	When KGDB is enabled and DDB disabled, kernel boots up to
	a point where it waits for the remote system to connect.
	Once the remote system attempts to connect, it faults with:

		kgdb: caught trap 0x6 at ...

	Where ... is in the cn_check_magic macro in com_common_getc()
	or com_common_putc().
>How-To-Repeat:
	See above.
>Fix:
	Unknown.  Filing so it doesn't get lost.
