Re: kern/48027: nfsserver module doesn't work

[Paul Goyette <paul%whooppee.com@localhost>]

OK, some more experimental results...

I have a total of six machines, all running the _identical_ kernel, 
identical modules, and identical userland.  Hardware configurations are 
all similar, but NOT identical, and there are five different ASUS 
motherboards in use.

Test #1 simply involves starting nfsd manually, and then stopping nfsd. 
This results in an auto-load of the nfsserver module.

Test #2 is a manual modunload(8) of the nfsserver module.


        Machine    Motherboard   Test #1    Test #2
           1       M4A88T-M      OK         Panic-A
           2       M4A88TD-V EVO OK         Panic-A
           3       M5A99X EVO    Panic-B
           4       M4A88TD-M     OK         OK
           5       M4A88TD-m     OK         Panic-A
           6       KGPE-D16      Fails to   Panic-A
                                 initialize

           6-GEN   KGPE-D16      OK         Not tried

           3A      M5A99X EVO    OK         Panic-A

Panic-A is reported at mutex-vector_enter

Panic-B is reported at nfssvc_addsock+1e5

Note that while machines 4 and 5 are identical (except for network 
addressing and hard drive details), the results are different!

The entry for Machine 3A involves a modified nfsserver module, with a 
couple of extra printf()s.  This changes the behavior.

Something wierd is happening, for sure, but I don't have clue.

For now, my production nfs server will continue to run the GENERIC 
kernel (line 6-GEN above).....
