[Bug 1037718] Re: Intel wifi led is off after resuming from suspend
I have narrowed the problem further to commits in 2.6.39, likely
somewhere in the splitting of iwl3945 drivers into iwlegacy directory[1]
I am struggling to get any further narrowing it down as either I am
facing kernel build issues or wireless is not working on the builds that
are in the middle of iwlegacy commits.
I will report this upstream and update with url.
[1] https://git.kernel.org/cgit/linux/kernel/git/stable/linux-
stable.git/log/drivers/net/wireless/iwlegacy?h=linux-2.6.39.y
** Description changed:
I have set the wifi "options iwlegacy led_mode=1" in
/etc/modprobe.d/wlan.conf to stop the led blinking, which works as
expected. The problem I have found is that if I suspend the laptop then
upon resuming the wifi led is permanently off yet the wifi still works
properly.
Also it is not just suspend that affects the LED, disabling wifi from
network menu or using the hardware wifi switch on the laptop results it
the same problem that the LED is permanently off after turning wifi back
on.
- This is regression going from kernel 2.6.38 (Natty) to 3.0 onwards.
+ This is regression going from kernel 2.6.38 (Natty) to 2.6.39 (Oneiric).
Note: I am not sure if it was clear enough that when the led is set to
blinking there is no issue with it being off upon resume etc.
WORKAROUND: To get the LED back on without rebooting reload the module:
rmmod iwl3945 && modprobe iwl3945
WORKAROUND: For the suspend issue is to add to /etc/pm/config.d/modules :
SUSPEND_MODULES="iwl3945"
