Radeon fb issue: invalid framebuffer id kernel 3.2.12

Radeon fb issue: invalid framebuffer id kernel 3.2.12

[Fabio Coatti]

Hi all,
I'm setting up a new laptot with Advanced Micro Devices [AMD] nee ATI
Seymour [Radeon HD 6400M Series] card, using radeon drivers. I'm
facing an issue for wich I found a lot of references but no actual
solution, so I'm asking here for some help

Basically it works quite fine, except for fb.

description of the issue:

at boot, once fb is fired up i get a black screen, afer some usual
boot messages. Connecting via ssh I can launch X and all works just
fine; however with ctrl-alt-F1 the screen freezes immediately with
this error in dmesg:
drm:drm_mode_getfb] *ERROR* invalid framebuffer id

some more debug lines:

[drm:drm_helper_probe_single_connector_modes], [CONNECTOR:23:VGA-1]
[drm:radeon_atom_dac_detect], Bios 0 scratch 40000 00000001
[drm:radeon_atombios_connected_scratch_regs], CRT1 disconnected
[drm:drm_helper_probe_single_connector_modes], [CONNECTOR:23:VGA-1] disconnected
[drm:radeon_lvds_set_property],
[drm:drm_mode_getfb] *ERROR* invalid framebuffer id


If I hit ctrl-alt-F7 all work just fine: screen unfreezes and I can
work without other issues.

Perfectly repeatable.

I can provide more debug logs and data, if needed; just place me in
CC: list as I'm not subscribed to this list.

the invalid framebuffer id isn't fatal, however it sounds like you
haven't got CONFIG_FRAMEBUFFER_CONSOLE
or haven't loaded fbcon.

Thanks for the heads up!
