Fixed in "bugfix/sdmem_on_intel_gpu" (based on devel) in my repo :D
Please test that it fixes it for you too, and please verify that the
memory still is wiped.
If that is the case, the screen corruption I had and this regression was
related. The screen corruption does not occur anymore, and I actually get
erasing progress written with * during erasing, something I didn't knew
existed :)
The "i915" driver (and its dependencies) must be loaded before sdmem
starts wiping. I guess the problem was that the GPU still believed the
video memory was mapped to a System RAM region, but the kernel thought
that memory was unused. By loading the driver it is reinitialized
properly.
PS: only tested by patching the affected ISO, I haven't really built the
branch.
