Comment 46 for bug 367060

I think the original reporter, Tillanz and myself are both fairly confident that the root cause is defective USB hardware in some way. The problem is really that the defective hardware makes the console unusable.

At least in my case removing the defective hardware is not really an option since it's a laptop with internal usb hardware.

Uncommenting 'kernel.printk = 4 4 1 7' in /etc/sysctl.conf doesn't seem to have any effect on silencing the messages, but a bit more googling on my part might come up with another way of silencing them I guess.

The same problem is still there with the lucid RC btw. I'm also finding that having lots of messages printed to the console also seems to affect suspending the machine, but not consistently.
