I was logging in on vc2 to find out why my Quake3 game was being
sluggish and this came up right after agetty:

Unable to handle kernel paging request at virtual address 762f7473

I was still able to log in afterwards (I still haven't rebooted the
machine and I'm typing this on it) but hotplug processes are reproducing
like rodents and I think the kernel is starting them (I kill everything
related and they all come back). This was around 5-10 minutes after my
first boot with this kernel.
