Hi all,

I'm running Aptosid 32bit KDE on a DELL D400.

I installed it few weeks ago with an ISO file containing the kernel 3.1.-6.slh.1-aptosid-686.

The integerated - lspci -: Broadcom Corporation BCM4318 AirForce One 54g worked out of the box (which was a great experience Very Happy).

Kern.log told me:
- b43-phy0: Broadcom 4318 Wlan found (Core rev 9)
- b43-phy0: loading Opensource firmware 410.31754

After upgrading the system to Kernel 3.2-8.slh.2-aptosid-686
and 3.2-9.slh.1-aptosid-686 Wlan is dead at all, means neither the Broadcom chip works any longer nor other wlan (usb) devices work.

But Kern.log still tells me the same information like before (chip found, firmware used and so), iwconfig tells there is wlan0 - but ceni doesn't find any SSID any longer. I also reinstalled wpasupplicant and the - after kernel update - missed TG3 Modules. I used the opensource B43-driver and tried with broadcom firmware - same results !

Starting the computer with the old Kernel 3.1-6 brings the WLan back, SSIDs are found, connection gets established - but network doesn't work, destination hosts are unavailable .. btw. eth0 still works ..

I also tried to use alternatives: NDiswrapper-dkms won't even install (error occured while building module); ndiswrapper-common/-utils-1.9 - all from the repos - don't work, modprobe ndiswrapper -> not found; ndiswrapper -v module to "old" .. argh ..

System and Packages are atm up-to-date ..

That's driving me nuts .. any suggestions ?

So long

I cannot reproduce that on bcm4318 (neither do I see any problems with ipw2200, rt2860, rt3572, rtl8185, AR2425 or AR5008) so far, but I'll try to get my hands on a system with bcm4306 on monday.

Please make sure to purge all remains of ndiswrapper, it's basically unmaintained upstream for ~3 years and tends to leave more problems behind than it might solve.

I can reproduce this problem with BCM4306/3 on a 32 bit PIII system and am confident to have found the cause, however I do need the full "dmesg" output from both 3.2-9.slh.1-aptosid-{686,amd64} (broken) and 3.2-9.slh.2-aptosid-{686,amd64} (hopefully working) I just uploaded, to debug this further. Feedback about the effects of 3.2-9.slh.2-aptosid-{686,amd64} is needed.

'Cause I need WLAN connection I reinstalled the latest iso Embarassed and everything is fine Smile Do you need any further help with 32bit ? Seems that your request is targeted to 64 bit systems ..

No. 686 isn't 64 bit.

Since you just re-installed, deliberately breaking your system by installing the broken kernel again, copying the info, trying the new kernel, copying that info might solve the problem more thoroughly than just re-installing.

The regression has been debugged with the upstream maintainer and was (hopefully) fixed for good. Affected were single core CPUs (one of the reasons why I couldn't reproduce the issue on my, dual-core, amd64 system with BCM4318), which didn't process interrupts correctly anymore after a recent stable fix.

Feedback if the current kernel does indeed fix your problems is still very much appreciated (needed), just take care that upgrades aren't safe right now, while KDE is still in the process of upgrading.
