Good. It looks like the graphics issue is related to the e100 nic.
If I remove it, the corruption goes away. The corruption starts roughly
when I used to see the "bad mpa" messages before the namespace fix, so
it seems like the windows e100 driver is somehow interfering with VGA.
BTW, it seems like a bad idea to me that we're exporting the range
0xC0000-0xDFFFF as system RAM. This is typically VGA ROM space. Should
this perhaps be reserved memory? Thanks,
