Jeff, The fix for https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1709123 is in proposed could you please test the proposed kernel and change the bug tags as verfication-done-zesty, since we dont have the 2.0 firmware at canonical yet?

This erratum affects QDF2400 v1.1 silicon. The software bug is only exposed when using Firmware 2.0 or later (estimated release October 2017). To ensure compatibility with future firmware, the Ubuntu kernel should apply the aforementioned patch. Without this patch, customers using the 2.0 firmware and 1.1 silicon might not have a functional UART console, either sometimes or always. It is expected that this problem does not occur with 2.0 or later silicon. [Test Case] Upgrade firmware to v2.0 on a QDF2400 server with 1.1 silicon, and the kernel should fail to boot, with the patch applied, we should see no boot failure. [Fix] Following patch in linux-next fixes this issue: 37ef38f3f838 tty: pl011: fix initialization order of QDF2400 E44 [Regression Potential] This is a bug fix to tty driver and limited to qdf2400. Low risk.
