--- Comment #49 from Roger Olofsson <[email protected]> ---
I can see the logic pointing to create context since something happens in the
ioctl. It's strange that setting breakpoints there (context) doesn't break
though. It's almost as if it doesn't reach that part of the code?
I don't know if the below is relevant at all, grasping at straws now in the
heat. Nothing new is logged to dmesg after a forced assertion -> SIGABRT.
Looking at the sheer number of commits for drm-515 and comparing that to
linuxkpi the probability that bug is in drm is most likely higher than that the
bug is in linuxkpi?
Comparing drm-510 to drm515 looks like there's alot of restructuring which is
probably related to corresponding changes for linuxkpi? Must have been quite a
task to rewrite.
