Title:
xenial/linux: 4.4.0-186.216 - Problem with NFS mount
Status in linux package in Ubuntu:
Confirmed
Bug description:
Xenial Package: linux-image-generic (4.4.0.186.192)
Since Xenial Kernel upgrade to version linux: 4.4.0-186.216, there is
a problem with the NFS mounts, when the NFS Server has a timeout.
The journal and syslog are reporting thousands of the following messages per
second
Jul 30 09:05:07 ... kernel: [ 280.904750] xs_tcp_setup_socket: connect
returned unhandled error -1
The server becomes instable and OS hungs. Reboot resolves the issue
until the next NFS timeout occures.
using the previous kernel Linux 4.4.0-185-generic resolves the issue.
