A couple of hours ago, I had X with window manager and application running (PS/2 mouse works, too). There is only one small problem left, when scrolling the X screen down. Looks like my "hardware" scrolling has some problems with graphics. > DBE has a nasty property, it can be delayed until some write access > is written back from cache to memory.

This would give us some chances to find the real culprit. But it still hasn't happen again. > Some places in the kernel also pass uncached addresses to MAP_NR().
