This is a firmware bug.No sure if it is exactly the same thing as, but it sure does look like:

http://linuxwimax.org/bugzilla/show_bug.cgi?id=13


A fix is in the works, but the firmware release ETA is still unknown. As well, I don't know if there is a planned fix for the 5150 firmware that would fix this.

Does the bug still happen if you completely blacklist the iwlagn module and reboot?
Comment 2 Roman Sergeev 2010-10-05 13:01:33 UTC
hm...
if i blacklisted i2400m & i2400m_usb
iwlagn works fine

if i blacklisted iwlagn - nothing positive happens
Comment 3 Iñaky Pérez-González 2010-10-07 20:51:30 UTC
> if i blacklisted iwlagn - nothing positive happens

Was this?:

0.1 killall wimaxd
0.2 wipe logs /var/log/wimax/*

and then 

a.1. blacklist iwlagn
a.2. reboot (power cycle)
a.3. start wimaxd
a.4. nothing positive happens

or

b.1. blacklist iwlagn
b.2. rmmod iwlagan
b.3. start wimaxd
b.4. nothing positive happens

?

Please attach wimax and kernel logs in any case.

THanks,

(a) & (b) 

i mean that both modules does not working in same time 

bug about i2400 - https://bugzilla.kernel.org/show_bug.cgi?id=19352

in 2.6.35-r10 all works fine (iwlagn module loading)
i2400 does not conflict with iwlagn
and don't need to do blacklist i2400

ps: this bug about iwlang 
not a wimax bug :)

Ok, in a sense, that is expected.

The 5150 has a single radio chain that is shared between WiMAX and WiFi. Both cannot be turned ON at the same time.

However, it should be possible to have BOTH modules loaded at the same time, as long as only one radio is ON at the same time. This used to work before (at least I have done it).

I don't have any 5150s handy now, I need to hunt for one.

Can we do this quick test?

blacklist iwlagn
reboot
modprobe i2400m
start the daemon
turn the radio off (wimaxcu roff)
modprobe iwlagn

does wifi work?
Comment 6 Roman Sergeev 2010-10-10 17:31:30 UTC
hi

about test:

blacklist iwlagn - ok 
reboot - ok 
modprobe i2400m - automatic load
start the daemon - ok

     rfkill say that wimax-soft blocked

turn the radio off (wimaxcu roff) -nok
     
     device UnInitialized

modprobe iwlagn - ok
:)

because https://bugzilla.kernel.org/show_bug.cgi?id=19352
wimax not working for me
