Why should this have changed. This anoying bug is existing since 15.10 and even if there are several tickets nobody funkin cares!
https://bugs.launchpad.net/ubuntu/+source/linux-lts-wily/+bug/1583191 https://bugs.launchpad.net/ubuntu/+source/linux-lts-xenial/+bug/1579803 And yes i'm not dump. I tried the latest kernel...even 4.13...oh wonder...nothing changed.... AND NO this ic NO UPSTREAM BUG! This is Ubuntu related ONLY!!!!!! I'm using DEBIAN 9 with exactly the same Samba settings, just an other samba version and kernel 4.9. MY guess is this is a Samba related problem! It happens ONLY when there is heavy use on Samba!

It was confirmed but never fixed..... This is a KVM guest with 17.04 (upgraded from 15.04->15.10->16.04->16.10). Its just am samba file server attached to a AD. When lage files get transfered (e.g. AD profile) samba gets stuck and prioduces a kernel hang. I install a Debain Stech (Kernel 4.9 and samba 4.2.14) for dual boot for testing, copied the smb.conf and attached it to the AD. I never get any errors like this for month, so this IS a Ubuntu related bug!
