Something that's been bugging me of late: the Oops output is quite expensive 
in lines on the terminal, which means if you get a couple of oops before the 
kernel stops, you're unlikely to see the one that fired first.

To help with this, would it be good to use the following form for the initial 
part:

 kernel BUG at time.c:99, invalid operand: 0000
 CPU 1: EIP:    0060:[<c011bd14>]    Not tainted
 EIP is at sys_gettimeofday+0x84/0x90
 eax: 0000004e   ebx: cef9e000   ecx: 00000000   edx: 00000068
 esi: 00000000   edi: 00000000   ebp: bffffad8   esp: cef9ffa0
 ds: 0068   es: 0068   ss: 0068   eflags: 00010246 [textflags]

Where [textflags] is some arch-specific representation of the flags word.

Also, in the same vein I would like to be able to say (as a kernel option):

if kernel-oops {
 copy console output to [printer|serial] port
}

[printer output == ascii only, of course]

Regards,

Ruth
