Public bug reported:
Binary package hint: samba
Mounting a CIFS share off an IBM N3300 filer (== NetApp FAS 2020), I
experienced some file managers, applications, ... to more or less
regularly lock up / don't do anything while trying to browse folders.
Looking more into this, it seems the problem is more basic. The thing is
mounted using cifs:
//192.168.1.252/data on /opt/filer type cifs (rw,mand)
Looking at dmesg, these errors do appear more or less frequently when
trying to read off the filer:

It happens once in a while copying things off the filer using the shell, and it
happens almost reliably when browsing to the share using any visual file
manager.
