This issue seems to occur with kernels > 4.10 and < v4.19 and got already fixed with applying two patches to bionic (and cosmic) in LP 1810998 - thx to Mauricio Faria de Oliveira. Hence this bug here can be considered as done and I mark this bug as a duplicate of LP 1810998. ** This bug has been marked a duplicate of bug 1810998 CPU hard lockup with rigorous writes to NVMe drive -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1805693 Title: User reports a hang on 18.04 LTS(4.15.18) under a heavy I/O load To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1805693/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
