In this one, I don't see any issues with oplock breaks. I also don't
see any calls that are taking longer than expected. I do see a bunch of
page-sized reads in the capture for what appear to be sequential reads.
Reads also seem to be serialized, which is makes me think its falling
into the readpage codepath.

There were some fixes to rsize handling in later kernels, so it's
probably worthwhile to test those before you do too much debugging.


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
