Comment # 6 on bug 109955 from Jaap Buurman

Another question: What is the output of the following command for you guys?

cat /sys/class/drm/card0/device/vbios_version 

I am running the following version:

113-D0500100-103

According to the techpowerup GPU bios database, this is a vega bios that was
replaced two days (!) later by a new version. Perhaps issues were found that
required another bios update? I might install Windows on a spare HDD and try to
flash my Vega to see if that changes anything.
