I'm having the same problem on a Sony PCG-Z600LEK. I cant even boot. I
seem to recall being able to use 7.10 fine, but the message was always
flooding the message log (and using the tty was impossible). I cannot
install 8.4 - it hangs on the boot screen for a while, then drops to tty
and floods it with debounce messages.

Im having the same issue with Mint (naturally since it's ubuntu based).
I also have the problem with the latest Debian (although i installed
just fine, but the system went down after an update - so it's probably
kernel related). I'm going to try non debian distros like Fedora but i
expect the same. I will also try using older versions although this bug
is reported across multiple kernels and has cropped up in the past.

Im also getting:

usb 1-1.3: device not accepting address xx, error -71


device descriptor read/64, error -71.

I have no bluetooth in this laptop, have no usb devices attached and i
have even tried opening it up and manually disconnecting the usb ports
from the motherboard (so it's controller related) and the issue still
remains. All the stuff about legacy etc... is useless as are all the
kernel parameters. As of right now this laptop is a paperweight until
this issue is resolved.
