Re: [19.666764] Disabling IRQ #23

The only proprietary modules
Atheros and Fglrx. Which confuses me, due to the message giving
Info on USB. As for the login,
On a MacBook I need uhci
To use the keyboard. When this
Goes off I can type, but results
In the letter duplicating itself I.g.
Typing the letter * results in **
As for using ssh, no.
I guess as a workaround I can try and change my login name and password
With double letters so I can grab a copy of dmesg

What's the proprietary module that's tainting it? Ideally we'd like to see it reproduced on an untainted kernel, but depending on what it is, it may not matter.

When you say you're not able to log in, is that because the keyboard is unresponsive? It appears to be affecting USB, so I'd be curious to know if you can ssh into the box, or log in with a PS/2 keyboard. Of course, some PS/2 ports are connected via USB under the hood, so the keyboard might not tell us much.
