rt2800pci - ksoftirq takes 100% CPU

[Loiseau Lucien]

Hi there,

I experience some trouble with my RaLink RT3090 Wireless 802.11n 1T/1R
PCIe card. I'm trying to set a wireless access point with it. I'm
running a Debian Squeeze with kernel 2.6.32-5-686.

at first i was using the shipped rt2860sta but since it's not a mac80211
driver, i couldn't use hostapd and iwconfig mode master was not working.
I eventually installed different stable version of compat-wireless and
ran the driver rt2800pci. If i could set a running access  point, i
often end with an unloadable module whith a ksoftirq taking 100% of my
CPU. Once this "ksoftirq" problem arises, there is no way to  unload the
module.

does anyone ever experience this card and make it work fine ?
I can provide more information if needed.

Lucien.
