Well 4 hours running with multiple reboots (our testsuite reboots every 30 minutes to test the watchdog). So far it has only lost 70 bytes out of 40MB of data sent between uart7 and uart8 (and we are pretty sure the serial test has a small bug that causes a few bytes to be lost right after a reboot sometimes). The reason I am even trying the new driver today is that we were seeing soft lockups on the CPU whenever the serial ports were being tested, usually in less than 5 minutes, so 4 hours without a lockup is a good sign. No idea what might be wrong with the old omap serial driver, but it seems something is (unless of course we managed to break it somehow when we tried to solve its habit of dropping characters). I think I will stick with this new driver. Better long term future anyhow. -- Len Sorensen -- 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
