Mike,

what error do you get from userspace (i.e. from dbench)?

open("./clients/client0/~dmtmp/EXCEL/5D7C0000", O_RDWR|O_CREAT, 0600) = -1 ENODEV (No such device)

An interesting note is that I can't reproduce at all
with only one dbench process. It seems there's not
enough load.

I don't see how the kernel could return ENODEV at all.
This may be coming from our client-core.
