Hi all,

I have been trying to fix a problem for days. I am using Fedora Core 6 with the latest kernel 2.6.20-1.2925.fc6. I installed ndiswrapper and when I use ndiswrapper -l it says:
neta5agu : driver installed
This is the latest driver for the D-LINK DWL-G132 USB wireless stick. I was able to connect to internet once. When I shutdown the PC, the dmesg log says that it cannot halt the usb, PC shutsdown but I still see the LEDs are ON on the device. After I reboot the system, it just hangs. So, I decided to unplug it and plug it back in when the system loads but no luck, system just freezes.

Now, I can't use the device at all. When I plug-in the device, system freezes immediately. I tried 'rmmod' to remove the ndiswrapper module and plugged in the device and typed 'lsusb' and I saw the device in the list. However, when I used 'modprobe ndiswrapper' system crashed again.

In the installation instructions for ndiswrapper in Fedora for kernels 2.6.x it was mentioned that 4k kernel stack size might create a problem. There is a link to another site to download kernels with 16k stack size. However I cannot install them since my kernel version is higher then the ones that are listed there. I beleive that this "stack size" thing might be the problem.
I got so frustrated and hoping that I can get a response from you guys. Thanks in advance for your reply.

if you're using yum, you can actually uninstall the current kernel and kernel-source, then install a new one right after. You'll have to remember the packages that are also removed due to dependency issue.

I've done that once due to architecture error .

As for the wireless driver problem. I just wonder did you use "-a" option to lock the device's id as mentioned in official wiki ?

Well, I checked the kernel-header version and the kernel version and they match. I already mentioned that I use the latest kernel. I also tried to lock the device id with -a parameter, using the lsusb's output as device id, but no luck. Sometimes, very rarely, I can connect to internet, but kernel always freezes when I use 'rmmod' to remove ndiswrapper.
So the system can never halt the usb while shutdown. I also suspect that the system gets slower and slower after sometime when connected. Thanks for the reply infwonder.

Well, I was simply thinking that maybe you can try to re-install same version of kernel with other stack size (not 4k)
