Comment 65 for bug 1791312

today I've updated the kernel to the current version 4.15.0-54 and ... the screen flickers again (!!!)
while the version from is working perfectly!!!
The differences:
current kernel 4.15.0-54: radeon.ko version: 2.50.0; module-size: 2342342
kaihengfeng kernel 4.15.0-52 unsigned: radeon.ko version: 2.50.0; module-size: 2343086
So the module in 4.15.0-54 seems NOT to be the same as that one corrected by Paul Dufresne / Kai-Heng Feng.
And: wouldn't it be a good idea to change the radeon.ko version-number too to identify the different versions?
