** Description changed: - An alarm 'beep beep' output during system boot at BIOS phase. - [Steps to reproduce] - 1. Install system with sutton-mccarthy-bionic-amd64-20190801-154 image. - 2. Reboot system. + Since this fix is still in the maintainer's tree, I add the UBUNTU: SAUCE: + prefix in the patch title. - [Expected result] - No alarm 'beep beep' when system boot and poweroff. + And this patchset is fixing a bug in the oem project, so please merge the + patchset to OEM-B asap. - [Actual result] - An alarm 'beep ...' during system boot at BIOS phase. + [Impact] + We often hear the Beep noise when a couple of LENOVO laptops reboot, the + reproduce rate is about 3/10. - [Failure rate] - 100% + [Fix] + make the codec enter D3 before rebooting or poweroff, this can fix the issue. + + + [Test Case] + Tested on those LENOVO latpops, reboot 50 times, didn't reproduce the + noise issue. + + + [Regression Risk] + Low. We tested this patch on different lenovo and dell laptops, they + all worked well as bfore.
