I noticed that the broken kernel is apparently some self-built kernel,
possibly with extra patches. Still, I'd like to make sure it works fine
if at all possible.
Could you add the following kernel parameters to the command line of the
noexec=off nopat acpi_enforce_resources=lax highmem=0K iomem=relaxed
The character after "highmen=" is a zero. A combination of these
parameters may fix it.
