[OpenAFS] problems with ubuntu 18.04 client

[martin.flemming@desy.de]

Hi !

In the last days we're getting more and more messages from users about 
having problems accessing their home-directories or subfolder or the hole 
user-tree /afs/desy.de/user is missing ...

Using ubuntu 18.04 with the regular openafs-client 1.8.0 ~ pre5-1 and 4.15.0-34-generic kernel ...
Server are running with mostly 1.6.22 / 1.6.23 with Centos7 ...

Are any problems known here with this combination ?

Solution seems to be only a reboot of the system ... Unfortunatley i've 
got not time to analyze one of these Desktops, because the user report 
this problem afterwards of the reboot ...

Thanks & Cheers
