So, it looks like bug 1830433 didn't fix this problem... assuming it's still an x86/mm issue, it'd be interesting to test another kernel (I've applied a few more x86/mm-related fixes).

This new test kernel is available at the same place:

https://kernel.ubuntu.com/~arighi/LP-1827884/

As correctly pointed out by Tyler, for the test you should remove "mitigations=off" and "nopti" and in case of success, please report the output of:

 $ cat /proc/cmdline

 $ cat /sys/devices/system/cpu/vulnerabilities/meltdown

Thanks again for all the tests!
