The sleep 2 with NetConsole does return, but much later. On my test system 
(bubinga, 405EP), a sleep 1 returns after approx. 13 seconds! This is related 
to the current implementation of "do_sleep()", just doing 1000 times 
udelay(1000). This should work of course, but the test in this loop for 
ctrlc() now introduces a lot of delay (timeouts, delays in the ethernet 
driver etc...).

As you my have noticed, I changed "do_sleep()" to use "get_timer()". This way 
it works without any problems. Please give the latest cvs/git version a try, 
and let me know if you still experience any problems.

Best regards,
