What version of samba?

When did you sup -current last?

This is really bizarre if its in the quota code, since you don't have
quotas enabled in the kernel. It looks like something is not registering
the QUOTACTL VFS method properly and is leaving it zeroed.

I'll try to reproduce this on my work machine if I have time.

Could you try it without CPU_WT_ALLOC in your kernel? Thats not a widely
used option.
