Mon Nov 30 12:39:59 PST 2009

Hi,
I have D-LINK DWA-547 PCI card on my Gentoo based PC.
I'm using kernel 2.31.r8 with the latest drivers from the linux wireless site.

I have the following error from the kernel :

After some time of using the wireless i get the following :

After that i have to restart hostapd service because i cannot connect any more.
Any ideas ?
