kernel log

The screen goes black after the radeon module is loaded. The only way I can get
any output is to blacklist the radeon module, load it via modprobe and then
change the resolution with xrandr from another computer via ssh.

I seem to get some sort of lockup if I don't blacklist the module, because then
I get a black screen at startup and I cannot even ssh into the machine. I tried
to enable netconsole from the kernel command line but I can't get it to work
(do I have to compile it statically?).

I tried this with 3.14-rc6. For reference, I'm including the log output I get
after I load the radeon module.

This card is an MSI R9 270X Gaming 4G.</pre>
