BTW, Looking at the current omap-git tree vs. the TI tree's I see that the sync_p_port() write calls are not there. If you add them in you probably will have a 80% drop in issues. To get 100 I think device attribute memory needs changing. If you look at old mails I gave some lengthy descriptions why they were there for ARM11. They were there based observed failures.
