If backing out rev 1.352 solves the problem, feel free to go ahead and either
back it out or add #if 0 around the changes.
But I think the fix is to change this:
/* We have a 1MB direct mapped region at KERNBASE */
if (pa < 0x00100000 && pa + size <= 0x00100000)
- return (void *)(pa + KERNBASE);
+ return (void *)(pa + offset + KERNBASE);
I've committed this as 1.356. If it doesn't solve it, then go ahead and back
out both 1.352 and 1.356.
Cheers,
-Peter
