@Seth : Yes, this problem is very confusing Since posting #8 i used a dedicated test system with a fresh kubuntu 16.04.1 installation on a well tested system. During the testing i modify /etc/fstab switching between noauto/auto options of nfs shares and later changing server uri to ip address or adding new entries from other servers.
And i install the test kernels, of course ;) Today i install the commit 50f208e18014589971583a8495987194724d56e4 again ... and it crashes as i said before. Unfortunately the kernel 4.4.0-54 is not available any longer from offical repos ... so i not able to test this one again ... but maybe this kernel had also the problem ?! At the beginning i was very confused because of some kernel crashes ... not on the first try but on the second or third try. In fact i found only one old offical kernel that do not have the problem and this is the 16.04.1 installation kernel 4.0.31 But i will try to find the last working kernel between 4.4.0-34 to 4.4.0-53 tomorrow. Mainline Kernel 4.10-rc4 and 4.9.4 both work since i modify server uri to ip address in /etc/stab > By that I mean you see a crash with nearly identical messages in the kernel log. Yes, of cource ... when i wrote the kernel crash this happend allways at the same place in the log with similar log entries > If there are multiple different issues going on it's best to try to focus on one at a time, if possible That is clear ... for example the resolv the ip from uri problem is secondary.
