Canonical, For a little more context, we have identified an issue in the test kernel you provided. After a sequence of 6 EEHs, DD will attempt to remove the adapter, which ends up hitting a BUG_ON. We think the above patch is a fix, but it's still not confirmed. Can you provide a kernel with that patch also applied for verification? It's still not upstream yet, but it has already been ack-ed by the driver maintainer, Keith Busch. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1602724 Title: Ubuntu 16.04 - Full EEH Recovery Support for NVMe devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1602724/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
