Asus U38N: Unable to get Video BIOS on Radeon HD 7600G

[Paul Menzel]

Dear Linux developers,


as reported in the channel #radeon on <irc.freenode.net>, I am not able
to dump the Video BIOS on my Asus U38N-C4010H with AMD Radeon HD 7600G
(Trinity A8-4555M).

I am using Debian Sid/unstable with Linux version 3.12-1-amd64
(3.12.6-2).

        $ cd /sys/devices/pci0000\:00/0000\:00\:01.0/
        $ echo 1 | sudo tee rom
        1
        $ sudo cat rom > /tmp/vbios.rom
        cat: rom: Input/output error

Am I doing something wrong or is this an error in the code?


Thanks,

Paul
