Title:
[Radeon HD 8830M / R7 465X] *ERROR* atombios stuck in loop for more
than 5secs aborting
Status in linux package in Ubuntu:
Confirmed
Bug description:
Ubuntu 18.04 freezes on every startup after GDM. This happens with
DELL Optiplex 7450 All In One with both an Intel graphics chipset and
an AMD Graphic card.
I have tested with kernels 4.15.0-29, 4.15.0-64 and latest HWE kernel
(5.0.0-29) ; all are affected.
As a workaround, it's possible to disabled the radeon card with
modprobe.blacklist=radeon kernel parameter.
I tried to dump the video bios rom
(https://dri.freedesktop.org/wiki/TestingAndDebugging/) without
success.
