I am experiencing the freeze regularly since I attached an external display through HDMI.
Dell Inc. Inspiron 5558/086DKN, BIOS A18 12/30/2019 Ubuntu 18.04.4 Freeze happens on kernels: 4.15.0-91 4.15.0-34 I didn't try other versions. I tried the ahci.mobile_lpm_policy={0,1} setting (#58) - with both 0 and 1 freeze happened again. I tried the extra X11 Intel settings (#42), but since then I removed the X11 intel driver package xserver-xorg-video-intel, as it is labeled as discouraged for HW newer than 2007, X11 doesn't recognize this configuration section. Some extra details: I have docker running. VirtualBox modules are loaded at boot. journalctl doesn't show anything right before the freeze. Can someone point me what sort of extra logging/tracing I can enable to poinpoint the issue? Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1798961 Title: Random unrecoverable freezes on Ubuntu 18.10 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1798961/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
