calim's response to this issue on #nouveau:
06:06 < calim> diegoviola: that has to be some issue with kernel not restoring
VRAM properly, the addresses the MP executes at look sane but the RAM contents
are obviously garbage
06:11 < calim> reducing the size of some buffer just hides the issue though
06:12 < calim> or it might step over the large/small pages boundary, could be a
hint
06:13 < calim> he's already thought about all that
06:13 < calim> s/about/of
06:13 < calim> will probably have to look at the kernel's suspend code next
06:14 < calim> I mean nouveau's suspend code
06:16 < calim> maybe double the size (from 32 KiB up to the original 512 KiB)
and check at which point it starts to fail to see if it really is the
large-pages allocation boundary
