Hello Junien, Based on my previous feedbacks, I've created the following PPA:
https://launchpad.net/~inaddy/+archive/ubuntu/lp1505564 With a Trusty HWE kernel (vivid) + 2 patches: nbd: Restructure debugging prints nbd: Fix timeout detection For you to use and provide me feedback. I've done minor tests and it looks like there are no regressions. Hopefully these patches will address the problem. If they do, I'll work on fixing Trusty, Vivid, Wily and Xenial. Cheers Rafael Tinoco PS: I'm still finishing kernel compilation and will copy packages to the PPA as soon as it is ready (it might take a few min/hours). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1505564 Title: Soft lockup with "block nbdX: Attempted send on closed socket" spam Status in linux package in Ubuntu: In Progress Bug description: Some of our nova compute hosts regularly freeze, sometimes for a few hours, with kern.log getting spammed with: block nbdX: Attempted send on closed socket and a few "CPU soft lockup" messages (see attached log).
