Description Stephane Marchesin 2005-01-29 16:38:58 UTC
When I use solo on ia64, it sometimes causes an MCA upon startup. That's because
a memset is done on the framebuffer memory during init.

Please refer to this message from Jesse Barnes to know why this is bad :

Here is a patch that fixes this by changing the memset into a for() loop doing
memory access one byte at a time :

New patch

Other drivers (r128 and mga) are affected too, this patches fixes all the
drivers that seemed to have this problem.

Should be fixed in cvs for ia64 and powerpc
