a different kernel bug?

after updates on mga2, i had quite some strangeness: first of all, after a 
little while of not yet rebooting, i got a complete hang of my system, SysRq 
keys worked, it appeared to be a CPU stall...

after reboot, my mouse didn't work. i replugged and then it did work.

looking through the logs on what happend, i saw the kswapd0 info, and later 
the hang in the form of continuous CPU stall INFO. but keyb/mouse hadn't 
worked (keyboard is PS2)

I did however note the following when booting up:

hmm... could the loading of ohci before ehci explain that mouse issue?


now, i admit to not rebooting right away, but this is likely less than an hour 
after doing the updates...
