Hi
I'm sure it's not a kernel issue:

S4 DC, s3fs file server (s3fs on the DC), kernel 3.4.6 -> Freezes
S4 DC, 3.6.3 file server, kernel 3.2.0 -> works fine
S4 DC, 3.6.7 file server, kernel 3.4.6, -> works fine

Summary: with a separate Samba 3 file server, the same kernel which 
gives freezes under s3fs, works correctly.

The problem is different every time. Sometimes it hangs completely on 
login, sometimes it logs in and then freezes for long periods.

Cheers,
Steve
