New 2.6.35 kernel keeps toggling bluetooth radio and wireless radio

Hi Rohan,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Hi
I tried the new kernel as well and still get the toggling problem,though it seems to be a bit less frequently now ( maybe once or twice every boot )
Attaching new dmesg log of : Linux kubuntu 2.6.35-020635rc3-generic #020635rc3 SMP Sat Jun 12 09:09:12 UTC 2010 x86_64 GNU/Linux

Hi
Now after 2 kernel updates my wireless is completely useless,the RF_kill operation has disabled wireless and i cannot use ifconfig to bring it up.
shadeslayer@kubuntu:~/ninja/kdegames$ sudo ifconfig wlan0 up
SIOCSIFFLAGS: Operation not possible due to RF-kill
shadeslayer@kubuntu:~/ninja/kdegames$ sudo ifconfig wlan0 down
shadeslayer@kubuntu:~/ninja/kdegames$ sudo ifconfig wlan0 up
SIOCSIFFLAGS: Operation not possible due to RF-kill

A new dmesg log is attached

It seems there has been a bunch of updates kernels released since this was last reported on. Could you test the latest -updates kerenel and let us know if the issue persists for you. Please report back here. Thanks.

Hi
I still get this a couple of times, usually the bluetooth radio comes online
and a notification pops up which indicates that my WLAN card was activated
