Thanks for the fast reaction! Some initial test rounds with just Patch 1 applied on top of 4.13.8 show no blue screens, will do more tests also with 4.14.3 on Monday and report back. 4.15-rc1 crashes for unrelated reasons, but I can re-run the tests once a stable-enough rc has been cut.. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
