I thought the recent reverts fixed this, but it seems that it's just become
a little harder to hit.

I'm seeing netconsole hangs on two x86_64 systems (2-way t61p laptop, 8-way
server).  Both use e1000.

With current mainline on the 8-way, create a printk storm with

while true
do
	echo t > /proc/sysrq-trigger
done

and the machine goes tits-up after about five seconds.
