Hello list,
Has anyone stumbled over a display problem with this kernel? Copying
the
.config from 4.8.14, tweaking with oldconfig and compiling left me
with a
blank display and no booting activity.
The display card is an AMD/ATI Tonga Radeon R9 380X and I load the
latest
microcode during kernel compilation. I have VIDEO_CARDS="amdgpu
radeonsi" in
make.conf. Fine with earlier kernel versions but not with 4.9.0.
Hi, I think I had a similar problem when I switched from the
proprietary AMD driver to the
radeon driver.
The configuration below works just fine on vanilla-sources-4.9.0 .
I have VIDEO_CARDS="radeon radeonsi r600" (for an older AMD video card)
AND (following a hint of Alan McKinnon) the following kernel
