CurrentDmesg.txt: [58189.152330] PM: suspend exit [58189.162027] Read-error on swap-device (253:0:361608) [58189.167038] Read-error on swap-device (253:0:361672)
"People die when they are killed". Specifically "Read-error on swap- device" kills you with SIGBUS. Mystery solved. I really expect if you looked at the crash, you would notice it is SIGBUS, with si_code == BUS_ADRERR (2). This means a read error when trying to load a page of virtual memory back in from swap or from the filesystem. There's a common bug which matches this, so please read #1776887 "Critical upstream bugfix missing in Ubuntu 18.04 - frequent Xorg crash after suspend". I'm sure this applies to at least some users who marked themselves as affected, or some duplicates of this bug. This particular kernel log includes some other errors as well though, so I can't rule out that they also have some relation. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1769819 Title: [nvidia] Xorg crashes after system sleep / wakeup, in libwfb.so+25597 → nvidia_drv.so+60a46c → [heap]+d35cb0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1769819/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
