Hi,
I am trying to get my my D-Link DWL-G650 wifi card working in my HP nx9005 Laptop whith the gentoo-2.6.12-r10 kernel.
This is the first and only PCMCIA card I have tried getting to work.
After emerging all the madwifi stuff and laoding the modules etc etc pluging in the card resulted in an super slow system and when the card is ejected a Kernel Panic.... Not nice. So I started from the beginning.. Recompilied my kernel with yenta_socket as a modules, removed all the madwifi modules from loading on boot, and removed pcmcia & hotplug scripts from boot.
Booed fine, inserted card and the system is still running fine, but as expected nothing is detected, a lspci shows that not even the cardbus is found.
Ok next step...
| Code: | | modprobe yenta_socket |
lspci shows the cardbus now, but when I plug in the card the system crawls to a halt and then when the card is ejected the kernel panics again.
Reading around a post suggested disabling "preemptive kernel" support, which is what I tried next. Now when I loaded yenta_socket... and plugged in my card everthing seemed to work. So I recompiled madwifi-driver and loaded the modules which then caused my system to grind to a halt. Sometimes ejected the card will cause the system to return to normal and othertimes it will cause it to panic.
Now by this time your all thinking the same as me.... it must be faulty hardware. But I have burned a copy of the KNOPPIX DVD which has madwifi support and runs the 2.6.12 kernel and the card works fine there.
Any ideas / suggestions (however strange and exotic they maybe) would be greatfully recieved.
Dan
P.S I have exlcuded irq 5 & 7 in /etc/pcmcia/config.opts which is needed for pcmcia to work on a nx9005 laptop.

Ok so I lied, I didn't mean to.. honest.
KNOPPIX doesn't support the card fully, it manages to load the modules and assign it the eth1, I set the ESSID and KEY fine using iwconfig but then when i issue
KNOPPIX also dies, I guess it might be a h/w fault then.
I think I know someone who uses madwifi drivers on there laptop, I'll have to ask them to try my card for me and see if I can borrow there card.
