Re: snapshot boot fails with error "entry point at 0x1001000"

Hi Mark,

on my Lenovo V130 the patch works. Now I'm able to boot the current
kernel again, without the need to remove the radeon and amdgpu driver
(https://marc.info/?l=openbsd-misc&m=159276382718317&w=2)

Thanks and best regards,
Sven
