Maybe this is a bit old but I would like get started on it again.
The difficulty is with a Compaq Deskpro XL 590 and the ethernet interface.
Ifconfigging lnc1 results in:
lnc1: Initialization failed
It the interface appears to be failing a test in lnc_init() from
/sys/i386/isa/if_lnc.c. Here:
if (read_csr(sc, CSR0) & IDON) {
...
} else
log(LOG_ERR, "lnc%d: Initialisation failed\n",
sc->arpcom.ac_if.if_unit);
read_csr(sc, CSR0) returns 0x8881. According to the specs on the AMD79C970,
this indicates ERR & MISS & INTR & INIT. Perhaps this is bogus information?
Would this the correct data sheet (lnc1 probe message below)? Based on
Whitaly's message, it might not be.

^^
this means it is in 32 bit mode?
If so then what options are available?

Any help with this would be greatly appreciated. The hardware is here
and it would be no problem for me to try out any patches or suggestions.
Would anybody be interested if I come up with a solution other than
plugging in an extra ethernet card? Just hearing the cold winds blow in
a desolate, lonely existence. Such is life.
P.S. I'm running 2.2.5 now.
