The TRM could be buggy or wrong; or your patch could be correct as far as the UART goes, but could be triggering a separate bug. We're reaching the end of the v3.9-rc fixes period, so we need to deal with the v3.9-rc regression quickly so folks don't wind up with a broken v3.9 kernel. Then the issue can be debugged and tested, and the revised fix targeted for the v3.11 kernel. > What settings of UART you were using to reproduce issue?

Could you be more specific about what information you're looking for, beyond what's in: http://www.pwsan.com/omap/testlogs/test_v3.9-rc5/20130331205513/pm/37xxevm/37xxevm_log.txt ? As you can see from the log, it's using UART1 at 115kbps -- init=/bin/sh, so no userspace to speak of. It's also worth mentioning that the 3730 Beagle XM here doesn't fail the PM test, UART3 at 230kbps in a "full" userspace: http://www.pwsan.com/omap/testlogs/test_v3.9-rc5/20130331205513/pm/3730beaglexm/3730beaglexm_log.txt - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
