wireless network stopped working after upgrading linux kernel to version 2.6.34

[Denis Laroche]

Hi all,

I had wpa_supplicant working perfectly on Linux, but it stopped working when
I recently upgraded the kernel to version 2.6.34. I'm using the wl driver
from Broadcom; I downloaded the latest distribution tar file from Broadcom
(as well as a patch for kernel >=2.6.33) and rebuilt it.

The version of wpa_supplicant is 0.7.2, and I'm using the same
wpa_supplicant.conf that was working before.

It might be an issue with the driver, because I see an ioctl error when
running wpa_supplicant with tracing.

Below is a transcript of running wpa_supplicant interactively with tracing.

Thanks in advance for any help.
