SpeedStream 1022 is not working on Ubuntu 9.04, kernel 2.6.28-14-generic

[sahoo]

Binary package hint: linux-wlan-ng

I compiled linux-wlan-ng from the svn repository.
It produced segfaults after loading the module prism2_usb.

I changes following file:
src/p80211/p80211netdev.c

in function wlan_setup:

#if (LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,28) )
        dev = alloc_netdev(0,"wlan%d",ether_setup);
#else
        dev = kmalloc(sizeof(netdevice_t), GFP_ATOMIC);
#endif
        if ( dev == NULL ) {
                WLAN_LOG_ERROR("Failed to alloc netdev.\n");
                result = 1;
        } else {
#if (LINUX_VERSION_CODE < KERNEL_VERSION(2,6,28) )
                memset( dev, 0, sizeof(netdevice_t));
                ether_setup(dev);
#endif
.....
                if (dev->_tx == NULL) {
                  WLAN_LOG_ERROR("null pointer netif_stop_queue\n");
                  result = 1;
                }
                else {
                  netif_stop_queue(dev);
                }

The driver is included in the kernel, so you are not supposed to build it yourself. Any particular reason you are doing this?

[sahoo (sahoo)]

The included driver didn't work.
Thats why I started doing this.

You may update the bug description to explain what the original issue is and the steps you have done to diagnose it. You only said you changed the code and it segfaults. What happens with the original driver? Please attach the full dmesg output.

Which change did you do to the code? Did it help?
