Mikko Rauhala, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue,please just make a comment to this.

Title:
8086:0085 Ad-Hoc wlan broken
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Ad Hoc wlan (hotspot) is completely broken for linux-
image-3.2.0-27-generic at least on my particular hardware. The bug
report says -24 because ubuntu-bug didn't allow me to edit that and
I'm running -24 as a workaround. No problem there. I tried linux-
image-3.2.0-26-generic to pinpoint the bug's appearance. It worked.
Adapter is 03:00.0 Network controller: Intel Corporation Centrino
Advanced-N 6205 (rev 34)
Snippet of syslog representative of the problem, under -27:
