Yes I am sure that's the same phenomenon. And here are the comparison
of those "WARNING" lines in recent days' kernel log:
// I bought this laptop on Nov 01 and installed (with wired network)
Arch Linux on the same day so no logs for Nov 01. On Nov 02 I started
to use wireless network, and here came the WARNINGs:

// At the night of Nov 04 I compiled Linux 3.12 and no more WARNINGs
on Nov 05, yet.
These timestamps are of UTC+8. I added "options iwlmvm power_scheme=1"
at about 2013-11-03 17:30 UTC+8...
I've been using Linux 3.12 for one day now, no more bugs about
iwlwifi.ko are encountered... Maybe this is fixed in Linux 3.12?
