p54 module blocks wlan network device

[dorpm]

Binary package hint: linux-source-2.6.22

On my machine I had no problems with the prism54 but the p54pci blocked the network device and it took me 2 days to analyse and to fix it.

After upgrading my ubuntu from 7.04 to 7.10 I was confronted with the problem that my so far reliable working network connection stopped working after finishing the upgrade process.

Regarding lots of postings to the supposedly buggy and not reliable working prism54 I blacklisted the module and tried to establish a network connection with p54 or ndiswrapper. For about a hundred times the system gave me a "ADDRCONF(NETDEV_UP): wlan0: link is not ready" after each "sudo ifup wlan0". The reason I found after heavy googling and reading about 10000 lines of error reports finally in /etc/udev/rules.d/70-persistent-net.rules. There I recognized that the p54pci module grabbed the device. Only when I blacklist all the p54 stuff I can reliably connect my net via prism54 or ndiswrapper. The difference between ubuntu 7.04 and 7.10 is that with 7.04 blacklisting of p54 was not necessary.

I recommend to consider that on some systems the prism54 module does his work as it should and with the p54 a network connection fails.

Hi dorpm,

I believe this may have been addressed in the current development kernel in the Hardy Heron Alpha release. It would be helpful if you could test the latest Hardy Alpha release: http://www.ubuntu.com/testing . You should be able to then test the new kernel via the LiveCD. If you can, please verify if this bug still exists or not and report back your results. Thanks.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug does not meet the criteria for a stable release update and is being marked as Won't Fix for the kernel version the bug was submitted about. You can learn more about the stable release update process at https://wiki.ubuntu.com/StableReleaseUpdates .
However, the issue that you reported is one that should be possible to test with the live environment of the Desktop CD of the development release - Hardy Heron. It would help us greatly if you could test with it so we can work on getting it fixed in the actively developed kernel. You can find out more about the development release at http://www.ubuntu.com/testing/ .
If you do decide to test with the development release of Ubuntu please comment on this bug report and include at least the minimal information requested at http://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks again and we appreciate your help.

Hi Leann,

I cannot find the LiveCD. From where is it downloadable?
