NetBSD crash-test-dummy.putnam 1.5W NetBSD 1.5W (CRASH-TEST-DUMMY) #42: Mon Jul  2 23:09:06 EDT 2001     nathanw@crash-test-dummy.putnam:/d/home/nathanw/work/sa/sys/arch/i386/compile/CRASH-TEST-DUMMY i386
Architecture: i386
Machine: i386
>Description:
	Typing control-T (the status character) when booting an i386
with a serial console causes a panic. The character must be entered
after init has started but before getty starts (ttyflags does not
affect it, apparantly).

 
>How-To-Repeat:
...
init: copying out path `/sbin/init' 11
Tue Jul  3 03:20:32 GMT 2001
swapctl: adding /dev/wd0b as swap device at priority 0
Automatic boot in progress: starting file system checks.
 ... press control-T
kernel: page fault trap, code=0
