Same thing since I upgraded to 4.15.0-151-generic on my laptop. Previously had 150+ days of uptime, now it crashes every few days, and up to 3 times a day.
Very similar behaviour than what Martin reported just above: when logging in to XFCE, it can crash easily, or when simply using the Desktop. When it happens, this is a hard freeze, the watchdog doesn't trigger (I waited for 1 hour), and even the sysrq keys no longer work (yes, these are enabled). Hardware: DELL Latitude 5300. To add some datapoints, here are my 2 last crash reports: ==> /var/crash/linux-image-4.15.0-151-generic.31533.crash <== ProblemType: KernelOops Annotation: Your system might become unstable now and might need to be restarted.
