Ndiswrapper kernel oops :(

My new 64-bit slackware is having internet/ndiswrapper problems. Namely, a kernel oops that kills ndiswrapper and in turn, my internet connection, as quickly as 1-10 minutes after bootup.
However, I read this guy seems to be using my current wireless adapter (WUSB600N) with success using open-source drivers! It seems to be the source inside the tarball, so here’s hoping it will compile correctly as 64-bit and work natively.
Update –
Well, I’ve compiled and configured the driver module, and I have good news and bad.
First, I’d like to note that the driver is hardly user-friendly, and requires manual editting of the makefiles before compiling. The regular `make` compile needs to be done as superuser, or else it fails (because it makes files in the root directory), and then the readme asks you to copy a .dat file to /etc/Wireless/RT-something (which means you have to make those directories first). I don’t see the point in copying that file over there yet, anyways, because I insert the module directly from the make’d source.
The good news, however, is that it works! I’m connected to the neighbor’s internet right now. Why, you ask, my neighbor’s internet? Because I kept getting timeouts on my home encrypted network (WEP as far as I remember). This (unsecure) one connected right away, however, which leads me to believe that I configured the makefile incorrectly before compiling. The readme was a little confusing. But, there were two options, so I suppose I’ll just go back and pick the other one, and recompile (hopefully with WEP support this time).
fucking ndiswrapper, always giving me shit.

make -C driver

from ~/ndiswrapper-1.53/driver/Makefile:
# By default, we try to compile the modules for the currently running

# version from the kernel sources.
KVERS ?= $(shell uname -r)# KBUILD is the path to the Linux kernel build tree. It is usually the

# a separate directory.
KBUILD ?= $(shell readlink -f /lib/modules/$(KVERS)/build)ifeq (,$(KBUILD))
$(error Kernel tree not found – please set KBUILD to configured kernel)
endif
I’ve tried setting KBUILD as /usr/src/linux-2.6.22.5, which is the directory of my kernel source, and /usr/src/linux which is the symbolic link to the former, and I’ve tried clearing the variable to nothing at all. None work.
uname -r seems to give Slack’s current running kernel version instead of LFS’, so after typing this, the next thing I will try again is rebooting and compiling from the actual LFS environment. Also, /lib/modules/linux-2.6.22.5/build points to /usr/src/linux-2.6.22.5.
edit; okay, that problem doesn’t exist when LFS is actually booted. Instead I get a warning about “kernel lacks wireless extensions” “wireless drivers will not work”, or something. I jotted it down as it scrolled by. So, it looks like I have to recompile the kernel with wireless extensions. I’m not sure what “wireless extensions” it’s looking for, but I can just modularize a few relevant-looking components and see if it suffices.
Broadcom WMIB-184GW + Ndiswrapper + Slackware

First, install ndiswrapper from source. I suggest the latest version from here. Untar it and do “make” and “sudo make install” from the command line. Or instead of using sudo just “su root” and do everything from there which would be easier because many of the upcoming commands require root privileges as well.
You’ll need the drivers for your chip which you can get here. You can either run this self-extracting exe under wine, which works well for me, or if you dual-boot Windows, run the program there. It will extract into the default folder “C:\cabs\BCM40100″, with another self-extracting exe, BCM_REL_4_100_15_5_WHQL.exe. Run that and it will extract by default to “C:\BCM_REL_4_100_15_5_WHQL”. Copy over the files bcmwl5.inf and bcmwl5.sys to your home folder (if you ran the programs under windows, just mount your windows partition under Slackware to copy them).
Now you can install your drivers under ndiswrapper with:
ndiswrapper -i ~/bcmwl5.inf
This should result in the command “ndiswrapper -l” displaying something similar to:
bcmwl5 : driver installed
device present
To disable the conflicting non-ndiswrapper drivers, edit /etc/modprobe.d/blacklist and add the lines:
blacklist b43
blacklist ssb
(bcm43xx should already be blacklisted in later versions of slackware, but make sure the line “blacklist bcm43xx” is there anyways, and if not, add it)
To configure ndiswrapper for usage on bootup, do:
ndiswrapper -ma
modprobe ndiswrapper
Slackware does not by default save your network settings, so what I did was add what I needed to get the network running to /etc/rc.d/rc.local. There was a /etc/rc.d/rc.wireless, but I found it simpler to do it this way. Here’s the example based on what I used:
ifconfig wlan0 up
iwconfig wlan0 essid "<your network name here>"
iwconfig wlan0 key <your encryption key here>
iwconfig wlan0 rate <optional - set wireless speed, ex: 54M>
iwconfig wlan0 channel <also optional - your channel here>
/sbin/dchpcd wlan0
