https://bugs.freedesktop.org/show_bug.cgi?id=110906 Bug ID: 110906 Summary: [Regression 5.2-rc4] Frozen screen with `Memory manager not clean during takedown.` Product: DRI Version: XOrg git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: pmenzel+bugs.freedesktop.org@molgen.mpg.de Created attachment 144521 --> https://bugs.freedesktop.org/attachment.cgi?id=144521&action=edit Linux kernel 5.2-rc4 messages There is a regression between Linux 5.2-rc3 and 5.2-rc4. The screen just freezes with start-up messages (mainly systemd notifications), and the login screen is not shown. Logging in remotely using SSH is possible. The X server cannot start as no screens are found. Linux logs the messages below. [ 11.452246] ------------[ cut here ]------------ [ 11.452697] Memory manager not clean during takedown.
