"orinoco_pci: Busy timeout" during initialisation

[Glenn Moloney]

Hi All,

I have been battling with the builtin wireless lan card on my Sharp
"Muramasa" PC-MM1-H3W laptop.

When loading the orinoco_pci card, I get the following messages:

orinoco.c 0.11b (David Gibson <hermes at gibson.dropbear.id.au> and others)
hermes.c: 5 Apr 2002 David Gibson <hermes at gibson.dropbear.id.au>

Same thing with orinoco_pci.o from 0.13a.

lspci -vv -s 0:0b.0 reveals:

00:0b.0 Network controller: Harris Semiconductor Prism 2.5 Wavelan

The interesting thing here is the "[disabled]" memory region.

I try to "enable" pci memory accesses with:

setpci -s 0:0b.0 command

reveals 0011 - which indicates memory access is disabled.

setpci -s 0:0b.0 command=13   # to enable Mem access

But - the command register remains set at 11. I can set other bits in
the register - but not the Mem bit.


Is there something I have to do to enable the card before loading the
orinoco module?

Any clues greatly appreciated.

cheers,
glenn.
