I'm just now realizing that the crashdump above may have been taken too late (when the kernel wasn't locked up anymre), because I could ssh to the server when I took it.
I was seeing the "block nbdX: Attempted send on closed socket" kernel log spam on the serial when I sent the NMI, but _perhaps_ these messages were just earlier messages that the serial was still catching up with. Anyway, I got 2 new dumps, and these 2 were triggered automaticallt by kernel.softlockup_panic so they might be better. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1505564 Title: Soft lockup with "block nbdX: Attempted send on closed socket" spam To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1505564/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
