Subject: 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
