> Here's my theory on what's happening:

Another possibility might be that e.g. PAT / MTRR attributes aren't properly
restored for some memory areas. Can you attach the following files from
before/after suspend/resume:

/sys/kernel/debug/dri/0/radeon_*_mm
/sys/kernel/debug/x86/pat_memtype_list
/proc/mtrr
