Comment # 3 on bug 1186825 from Ralf K���lmel

Created attachment 850148 [details]
kernel traces with kernel 5.3.18-lp152.75-default

i had again the problem on a system. Now the behaviour was different: 
1. the system had continuous problems until i reboot the system.
2. the NFS fileservers were available for other systems

I think that the main problem is the rpc behaviour with cpu stucks and not only
the reaction of the network layer to reset the network interface("ixgbe
0000:02:00.0 eth0: initiating reset due to tx timeout")
