mount_smbfs has terrible transfer rates on my 5.3-R box

Whoops,
Forgot to post my kernel configuration. After looking through it, I
just realized that I do have PREEMPTION enabled. Is this a likely
candidate for the problem?
(PREEMPTION fixes a very annoying sound distortion issue with the
emu10k1 driver/SB Live! 5.1 that I have on my box. Search the current
lists for 'sound distortion' or something and you'll find it).
I'll try to test this with a GENERIC kernel later on today.
Anyway, here it is:
