AMD A6-3400M not working on Linux kernel 3.0
I'm using Ubuntu 11.04 64-bit version.
Tried compiling kernel 3.0.4 and used the 3.0 kernel from xorg-edgers and neither of them work. No display on screen although the system does seem to be loading. This is on the Asus K53TA-BBR6 laptop.
Haven't tried newer kernel versions since kernel.org is down.
On Fedora 15 64-bit with latest updates and 2.6.40 kernel, also not working.
2.6.38 kernel uses VESA for both distros.
I think the A-series is a bit too new for even Ubuntu 11.04. Try an 11.10 beta or the equivalent work-in-progress Fedora.

Not working with Ubuntu 11.10 beta 1 64-bit dvd either. The menu shows up, I select live desktop option and absolutely no display. It does boot into the desktop though because I can hear the login sound playing.
Did you tried booting with nomodeset ?
I have the same board AMD a6-3400m with a Radeon ATI hd 6520. (Its on a HP notebook I got at a very good price...).
I'm still trying to make it work with the open source driver without success (x11-drivers/xf86-video-ati).
I'm on Funtoo (based on gentoo) with the 3.1.0-rc4-git2 kernel, and masked versions of Xorg and video drivers, libdrm, libkms, mesa, ...).
I had the same problem but I was able to connect to the machine with ssh from my other machine. You have to install & config sshd before in a chrooted shell on your machine.
I have enable the following kernel options for frame buffer :
and for radeon:
# CONFIG_FB_RADEON is not set
But I think You should set "CONFIG_DRM_RADEON_KMS=n" instead.
Take a look at http://xorg.freedesktop.org/wiki/radeonBuildHowTo
in case of trouble (black screen), if you use grub to start, try to edit the grub command and add "vga=711" kernel options or (radeon.modeset=0). I can't confirm now. But I think the AMD ATI Radeon HD 6520 is only usable with the proprietary drivers from ATI. This card is too recent right now (mid april 2011). May be in a few months it will be ready.
where can I get the SUMO microcode? my laptop also has a Radeon HD6650M so will I need to get firmware for that too?
thanks Perfmonk, will try that. problem is i can't see anything on booting the live CD, so can't install ubuntu 11.10. i might be able to install using the alternate iso and then I can try changing grub settings.

so radeon.modeset=0 won't work?
