Dear Linux graphics folks,
using the ASRock E350M1 with coreboot [1] and plugging in an external AMD graphics card,
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Cedar PRO [Radeon HD 5450/6350] (prog-if 00 [VGA controller])
first I get Linux message output over the internal card, but then after the following error message

the display just freezes although the system boots up fine otherwise as I could in over a serial line. Plugging the VGA into the port of the external graphics card did not seem to help either as the monitor stayed black.
Please find the output of `sudo lspci -vvv -xx` without and with the external card plugged in attached.
Do you have any suggestions, what the problem could be? Should coreboot set something up differently? Any suggestion what?
Thanks,
Paul
