** Description changed: + ===SRU Justification=== + [Impact] + Server console is extremely slow on ast, after the upgrade from 16.04 to + 18.04. + + [Fix] + Remove firmware/bootloader configured framebuffer device before probing. + + [Test] + User confirmed the patch fixes the issue. + + [Regression Potential] + Low. The fix is in stable tree, limits to one specific device, and other + DRM drivers already do this for a while. + + ===Original Bug Report=== After the upgrade from 16.04 to 18.04 my server console is extremely slow. It looks similar to the youtube clips mentioned in the problem described here: https://ubuntuforums.org/showthread.php?t=2399941 My server is attached to a KVM switch with VGA cable to a 1920x1080 LCD. It runs on an ASUS P9D-X board. Before the upgrade everything was fine. Now it is so slow that it sometimes even hangs during boot and goes into an emergency console where I just can do a ctrl-alt-delete as described in bug 1802469 ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: xorg (not installed) ProcVersionSignature: Ubuntu 4.15.0-42.45-generic 4.15.18 Uname: Linux 4.15.0-42-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 Date: Wed Dec 12 17:07:48 2018 SourcePackage: xorg Symptom: display UpgradeStatus: Upgraded to bionic on 2018-10-11 (62 days ago) - --- + --- ProblemType: Bug AlsaDevices: - total 0 - crw-rw---- 1 root audio 116, 1 Dec 15 07:22 seq - crw-rw---- 1 root audio 116, 33 Dec 15 07:22 timer + total 0 + crw-rw---- 1 root audio 116, 1 Dec 15 07:22 seq + crw-rw---- 1 root audio 116, 33 Dec 15 07:22 timer AplayDevices: Error: [Errno 2] No such file or directory: 'aplay': 'aplay' ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord': 'arecord' AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: DistroRelease: Ubuntu 18.04 HibernationDevice: RESUME=UUID=99dd75dc-dc37-4970-be5a-79d9244a3bcc IwConfig: - eth0 no wireless extensions. - - eth1 no wireless extensions. - - lo no wireless extensions. + eth0 no wireless extensions. + + eth1 no wireless extensions. + + lo no wireless extensions.
