I don't see how that could hang the server running on linux.
A failure to support digital signatures will prevent the
Windows AFS Client service from being able to process the
requests and send a response that the Windows CIFS client
will respond to.

I suggest you open a ticket in the request tracker and
attach to it the output of "fs trace -dump", aka %WinDir%\TEMP\afsd.log
assuming that you can generate one.
