Comment 79 for bug 43154

Appreciate your comments. You may have saved us a long time in going off in some wrong direction. ;-) As of now, turning IRQ off in the X Driver causes more frequent lockups than before. Even a simple glxinfo is a candidate for this lockup. I know timing problems are hell of a lot difficult to find, but we have no choice. Lacking open specs from the manufacturer, we have to do some blind hit and misses to get it.

Another thing, if it is a memory timing issue, I assume this will lockup during a readl, writel or during writes to some buffers. Maybe, if we can isolate this, we have a better chance to understand what the issue is.
