Tested again on 2.6.38 with patches pulled from patchworks and for me, the same test case seems to be passing. Here is the log: http://pastebin.com/ccEmTZS5 The above test case is executed on blaze and same result is observed with other OMAP2+ boards also. Can you please let me know which board and code base you are using for testing so that I can try to replicate the same. -Manjunath > -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
