2014/1/13 Grumbach, Emmanuel [off-list ref]:

Are you sure about step 1 and 5?
It seems completely weird that an existing file with a line commented out have any impact.
Can you please send the output of:
        cat /sys/module/iwlmvm/parameters/power_scheme
in both cases.

Hi, the point is:

* With "options iwlmvm power_scheme=1" -> everything's fine
* Without "options iwlmvm power_scheme=1" -> network is bad

Absense of the modconf file and a modconf with only one comment line
have the *same* effect - network is bad.

cat /sys/module/iwlmvm/parameters/power_scheme now returns 1, and the
network is good.

Also - what code base are you using?

What is "code base"...?

Since  this is surely not related to PCI, please remove them in your reply.
(I keep them here to have them see my mail :))

Done. :-)



English is not my native language so I checked if I misuse the phrase
"comment out": http://english.stackexchange.com/questions/33483/when-i-say-comment-out-does-it-mean-to-uncomment-something-or-comment-it

Seems not...
