Hi Jeff,
I downloaded nwfs0331 and tried bringing the module up on a 2.2.14-pre15
SMP system. The build goes without incident, but this repeatable oops
occurs when loading the module:
ksymoops 2.3.3 on i686 2.2.15pre15. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.2.15pre15/ (default)
-m /lib/modules/2.2.15pre15/System.map (specified)

Once in this state, the module shows up as "initializing" in lsmod and
cannot be removed (i.e. reboot time). The log discloses:

(oops follows..)
----------------------------------------------
A few questions:
- Does the module expect that an NWFS will exist at load time?
- If so, how can I create it? The linux utilities (which I notice have
been pulled from your ftp site) simply dump core immediately, doing
nothing of use.
Let me know how I can help.
