     I'm not having much luck getting my AT-1500 Lance-based Ethernet card
working on my new P-100 and would appreciate some help.  I can monitor
packets on my local subnet using BPF & tcpdump, but when I attempt to put
a packet on the line (e.g. with "ping host-on-local-subnet"), the ARP
request fails with:

     Dec 25 00:19:00 stealth /kernel: arpresolve: can't allocate llinfo

Interestingly this same kernel and same card config worked fine on my old 486.

     I've verified there are no Port/IRQ/DMA address conflicts (and have
tried several combinations anyway -- 340/12/7; 340/10/6; 300/12/7; etc)
with no change.

     Any suggestions on what I should try next (or thoughts on what
underlying problem this error might indicate?)

                                                Thanks,

                                                Randall Hopper
