Update: - SysRq commands keep working - Memtest86 and Disks -> SMART Data & Self Test didn't show any problems with memory or SSD
So I assume it's a problem that originates in kernel 4.15.0-151, as 147 doesn't show any of the problems and nothing else has changed between booting 151 vs. booting 147. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938126 Title: System hangs up or make filesystem read-only To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1938126/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
