Comment 120 for bug 182489

I followed the advice given in Bug 251252 given by Luks911 which restored the wireless connectivity. See below:

I am experiencing the same problem after upgrading to kernel 2.6.24-21 this morning. I posted a question (48094) seeking a solution for this issue. It has never happened in previous upgrades. Below is a copy of my question:

When I ran update manager this morning (10-15-08) my system upgraded to the kernel 2.6.24-21. Upon reboot my athi wifi card was no longer working so I reinstalled the madwifi files & rebooted again. When the system rebooted it stoped just short of the end on the status bar & the Caps Lock key light began to flash.

FYI-I am able to boot up using an earlier kernel (2.6.24-19) so this problem appears to be related to the kernel upgrade. This problem is also described in Bug 251252 but I saw no resolution as this is a new one problem due to the recent upgrade.

I am running 8.04 on a Compaq Presario 700 notebook.

Below are the steps & outputs (where indicated):

- Ran Update Mananger
- Rebooted into the latest kernel (2.6.24-21)
- Repaired athi card access using the following steps:
  - cd madwifi-ng-r2756+ar5007
  - make
  - sudo make install
  - sudo modprobe ath_pci
  - sudo reboot
- This is where the system locked up during the reboot process & where the Caps Lock light began to flash. The mouse pad light also goes from inactive to active. The system hangs in this mode indefinitely.

- Rebooted into 2.6.24-21-generic (recovery mode)
- Ran repair package option (dpkg)
- Rebooted and experienced the same problem
- Rebooted again into the 2.6.24-21-generic (recovery mode) to see what errors were occurring. Got the following message: kernel panic - not syncing fatal exception in intrupt

Is there a way to fix this issue or is a patch required? Thanks in advance for any help given in resolving this issue!

I read the same problem in Ubuntu-es forum, with that kernel update in Hardy and a Compaq Presario F700 (with Atheros AR5007EG).<br>
The aparently solution is:<br>
- Boot in recovery into kernel 2.6.24-21-generic<br>
- Uninstall de madwifi driver with:<br>
&nbsp;&nbsp;&nbsp;- cd madwifi_directory (madwifi-<wbr>ng-r2756+<wbr>ar5007 or another version, like madwifi-<wbr>hal-0.10.<wbr>5.6)<br>
&nbsp;&nbsp;&nbsp;- sudo make uninstall<br>
- Then install de linux-backports<wbr>-modules for your kernel version. With this package you can use the wifi using the ath5k driver: run<br>
- sudo modprobe ath5k<br>
if it's necesary.

I did the above which returned the wireless feature however when I try to connect via the wireless Internet programs such as Firefox act like the computer is not on-line. In my troubleshooting I noticed that the Atheros Hardware Access Layer device in hardware drivers is unchecked. Do I need to activate this?

Any suggestions are greatly appreciated!
