[Bug 162653] usb wifi causes kernel panic with Gutsy
Public bug reported: Binary package hint: linux-source-2.6.22 I have a Linksys wusb54g usb wifi adapter that worked fine under Feisty. I did a fresh install on another desktop with Gutsy and followed the same directions that I used for Feisty and got it to work perfectly. Once I rebooted the system the following occurred: I get a flashing keyboard and the system wont finish booting. I did a hard shutdown and on the next restart did the following: Hit escape and booted into Ubuntu 7.10, kernel 2.6.22-14-generic (recovery mode). If wifi dongle plugged in at boot, boot stops and gives this error message: [ 82.325884] Kernel panic – not syncing: Creation of kmalloc slab kmalloc_dma-2 size=2 failed. [ 82.325886] If I boot in recovery mode without the dongle plugged in I get a normal recovery boot and a root prompt. Once I plug it in, I immediately get the following error message: [EMAIL PROTECTED]:~# [ 75.112448] rt73: Firmware not load With either way, I get the two lights on the keyboard (next to the num lock light) flashing and the system locks up. If I allow the system to do a normal boot it boots fine. As soon as I plug in the dongle, the keyboard flashes and the system locks up, even after a normal boot. In order for the card to work again, I have to go through the whole setup procedure, then the card works fine. Once I reboot, it does not. I used the directions found at the following link to set up the card: http://ubuntuforums.org/showthread.php?s=c95e12ac8820b20798d6b536fff54bb9&t=512647&highlight=1feistymedic&page=4 Any suggestions? Wired ethernet does not cause this problem. ** Affects: linux-source-2.6.22 (Ubuntu) Importance: Undecided Status: New -- usb wifi causes kernel panic with Gutsy https://bugs.launchpad.net/bugs/162653 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Network manager no longer shows in the panel now. But I can still log on if I manually go into system, administration and network and enable it. Somehow the settings were lost. -- usb wifi causes kernel panic with Gutsy https://bugs.launchpad.net/bugs/162653 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I did the following in terminal: Code: cd /usr/src Code: sudo wget http://rt2x00.serialmonkey.com/rt73-cvs-daily.tar.gz -O /usr/src/rt73-cvs-daily.tar.gz Code: sudo tar –xvzf rt73-cvs-daily.tar.gz Code: sudo aptitude install build-essential linux-headers-`uname -r` Code: cd /usr/src/rt73-cvs-2007111213/Module Code: sudo make Code: sudo strip -S rt73.ko sudo make install Code: sudo ifconfig wlan0 down Code: sudo modprobe -r rt73usb Code: sudo modprobe -r rt2570 Code: sudo modprobe -r rt2500usb Code: sudo modprobe -r rt2x00lib Code: xhost + Code: gksu gedit /etc/modprobe.d/blacklist Code: paste after last line: # Blacklist rt73usb, as it is a non-functional beta module which conflicts with the working rt73 module. blacklist rt73usb # Blacklist rt2570, as it causes conflicts with rt73 blacklist rt2570 # Other modules that break rt73 blacklist rt2500usb blacklist rt2x00lib Code: sudo modprobe –v rt73 Code: sudo ifconfig wlan0 down Code: sudo ifconfig wlan0 down Code: sudo iwconfig wlan0 essid "my essid" Code: sudo iwconfig wlan0 mode managed Code: sudo dhclient wlan0 Code: sudo aptitude update Code: sudo aptitude upgrade Code: sudo aptitude install wpasupplicant libgtk2.0-dev Code: wpa_passphrase Code: gksu gedit /etc/network/interfaces Code: pasted: # The primary network interface auto wlan0 iface wlan0 inet static address 192.168.1.112 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 68.87.87.12 pre-up ifconfig wlan0 up pre-up iwconfig wlan0 essid "my ssid" pre-up iwconfig wlan0 mode managed pre-up iwpriv wlan0 set AuthMode=WPAPSK pre-up iwpriv wlan0 set WPAPSK="pasted psk info from two steps above" pre-up iwpriv wlan0 set EncrypType=TKIP After doing this it worked great, just like in Feisty. Until I rebooted. Then it broke. I can't even insert the card now to print out any info because as soon as I insert it, the system freezes up and does not unfreeze even after removing the card. -- usb wifi causes kernel panic with Gutsy https://bugs.launchpad.net/bugs/162653 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
