[Bug 602184] [NEW] Lynx last seed wireless card disconnects when PC too hot

[djipey]

Public bug reported:

Im' french and noob, so please excuse my english and my mistakes. I'm
going to try to do my best.

On Ubuntu Lucid Lynx, with a Aspire 7520 and a wireless card AR7005EG, when the temperature of my PC increases too much, i lost the wireless. For example, when the acpi parameter of my conky indicates 80°C (it's just an indication, just remember it's a little bit hot), my card seems to disconnect.
But when i downgrade to Karmic koala, i don't have anymore this problem. My acpi can go over 90°C whithout connection problem.
(I know it's hot, but it has been like that since the beginning).
When i just apply the updates to Karmic koala after an install (from the distibution proposed by default on ubuntu.fr), i have connection problems too. I think one of the packages installed during this update is responsible.

I tried to boot on the old kernel(2.6.31-14-generic) proposed during the
boot after an upgrade to Lucid from Karmic, and i still have the
problem. I think this is not a kernel or driver problem, because when my
PC is cool down or when i am on Karmic, everything is ok.
