Yenta CardBus problem

[Alberto Bengoa]

Hi people,


I'm having problem to put my orinoco pcmcia card to work on my laptop, a 
Compaq Presario 2140US.

This laptop have a Yenta CardBus bridge, as show lspci output:

When I put on the pcmcia slot a wifi card (orinoco gold, orinoco silver, 
wavelan ...) the hardware freezy with this warn message:

"BUG: soft lockup detected on CPU#0"

After systems boot up, analyzing the dmesg output, I found this messages 
that I think that's a possible problem source:

I tried to make a modprobe i2c_ali15x3 force_addr=0x0018 but this 
doesn't work. I tried to use wireless drive orinoco, orinoco_cs, wavelan 
and wavelan_cs, but no one works.

The yenta_socket and ali15x3 modules are loaded:

yenta_socket           16588  0
rsrc_nonstatic         14336  1 yenta_socket
pcmcia_core            42896  2 yenta_socket,rsrc_nonstatic
i2c_ali1535             7300  0

i2c_core               22096  2 i2c_ali1535,i2c_ali15x3


I'm running ubuntu breezy, with kernel 2.6.16.1 compiled by me and 
pcmciautils-013 from Linux Kernel 2.6 PCMCIA. I set UDEV = false at 
Makefile.

Maybe anyone can help me to fun a wireless network? :-)

Thanks,
