Problems with vaxuba/dm{f,x}.c and EMULEX CS41

[Sean McLinden]

There appears to be a problem with the Tahoe release
of the DMF driver. In particular, when the device is
an Emulex CS41 dmf look-alike, it autoconfigures OK,
but when the system goes into multiuser mode it crashes
with:

trap type 8, code = 89d55865, pc = 800395f8
Segmentation fault

The same kernel with a DMF32 does fine. Before I break
this apart has anyone seen this or does anyone know
what is the solution. We are working with the latest
Revs of both the CS41 and the UNIBUS.

Thanks.
