I'm attempting to see if this ROM bug is (a) known and (b) is or was fixed at some point. Based on what I know (or at least think I know) of how the ROM code lived for "OMAP3", given that you're seeing this on beagle and igep, it's a valid assumption that OMAP34XX is buggy. The question I have (and hope for resolution on) is if it's a problem on am335x/omap4 or later as well. If I follow how to reproduce this issue (and I think I do), assuming I can I'll setup an am335x platform in a similar position. > > If you don't want a patch for this bug please let me know.

Please be patient :-) Yes, thanks for working this issue through, I also appreciate it! -- Tom
