NetBSD 1.6ZC (GENERIC) #0: Thu Sep 25 19:14:10 UTC 2003
>Description:
nell requires options FULL_SPARC_BUS_SPACE to compile (this is not in GENERIC).

A kernel with options FULL_SPARC_BUS_SPACE but not nell boots without any problem. 

GENERIC ought to have (even if commented out) the following line:
wi*     at pcmcia? function ?           # Lucent WaveLan IEEE (802.11)

With nell and options FULL_SPARC_BUS_SPACE enabled, a -current kernel crashes when booting on a Voyager.

It repeatably panics at the same place.

Without debugging in the kernel, it panics after recognizing the ethernet interface (le0):
text fault: pc=0x42128 sfsr=164<PERR=0,LVL=1,AT=3,FT=1> sfva=0x42128
panic: kernel fault
halted

So, I built a kernel with full debug, ddb, etc.  It gets through autoconfiguration but panics after fsck, before setting tty flags in rc:
data fault: pc=0xf0cdbe4 addr=0x15f98160 sfsr=126<PERR=0,LVL=1,AT=1,FT=1,FAV,OW>
panic: kernel fault

I tried both kernels (non-debug and debug) on my SS20 and it had no panics.  It doesn't have a nell interface, but at least it's sun4m with vaguely similar hardware.  The kernel sources had been updated Oct 11, around 10pm PDT.

The dmesg of a GENERIC kernel on this hardware follows:

 FYI:

 maybe something has broken recently, but i'm running a nell with a
 wi in an ss20/712 under netbsd/1.6U (end-of-june-ish) no problems.

 That's probably the case.  Martin Husemann sent me private mail saying 
 he'd look into the nell issues.
