<pre>I solved that problem by use readl()/writel() func to access cpu virtual
address insteand of set address directly. such as use readl(&msg[1]) instead of
msg_type=msg[1]. and use the l/b endian transfer. But the new error ocurred
(error message) .
radeon:GPU lockup cp stall for ... more than...
I try to change the lockup timeout to longer but no use.
I don't know why??</pre>
