Hello,

Has anybody tried orinodo_cs 0.11b or 0.12b with success on symbol
Spectrum24 High rate11M card on mpc platform?
I've tried 2.4.18-pre3 and 2.4.19-rc3 kernel with orinoco driver. It
works
fine with intersil card. But
when i try it on symbol card, it always crashes. After tracing down i
find
it is caused by hermes_init(). It seems the
call to hermes_write_regn(hw,INTEN,0)  cause the crash. The ksymoops
also
suggest this function. It is just an io write. What can be wrong? And
most
strange thing is why it doesn't cause any trouble in normal intersil
card.

That's wierd - it is just a register write, so this sounds like a
low-level problem.  Is something about the card confusing the PCMCIA
system so it's reporting the wrong IO addresses?  Or maybe the timing
is a little bit different and something in the slot driver can't cope.

I would guess timing.  I have seen problems between different cards with
the same chipset fail on 8xx.  Usually timing is the culprit.
