[SOLVED] Lots of kernel messages after 3.1.2 update

I've just updated to kernel 3.1.2, on an Acer Aspire 3820G Laptop, and starting from the very first boot stages I get a lot of errors from the kernel that I think will soon fill up my /var/log directory This is an excerpt from tail -f /var/log/errors.log:

As you can see, the errors are very frequent!

What's going on? I think I'll go back to 3.1.1, but I'd like to know what's happening, why, and if someone else can reproduce it.
I guess the bug is upstream.
Any hint?

What is connected to that port. Not seeing a problem here so I'm guessing its specifically something you've plugged in via USB. A portable hard drive maybe?

EDIT: A quick google search gives this:

Some hardware just don’t work with ehci_hcd. ehci_hcd is now compiled into the kernel so the following is required to disable it:

cd /sys/bus/pci/drivers/ehci_hcd/
sudo sh -c 'find ./ -name "0000:00:*" -print| sed "s/\.\///">unbind'

However as I am simply reposting this from another forum I will not be able to help you further with this.

EDIT2: More information about driver binding/unbinding is here: http://lwn.net/Articles/143397/

Thanks llawwehttam, unbinding the device from the driver, as suggested in the article from lwn.net, makes the error disappear.
A simple

$ echo -n "1-1:1.0" > /sys/bus/usb/drivers/hub/unbind

did the trick.

same error, unbound with

echo -n "4-1:1.0" > /sys/bus/usb/drivers/hub/unbind

lost keyboard, rebooted and everything is A ok.

glad I didn't follow some other options as to quiet the error.

thanks guys.
