Hi


When I've checked  2.6.30-rc2 kernel and  I've got among other errors
with Wifi message below.
As I've noticed - some people were reporting this problem already earlier:

http://www.gossamer-threads.com/lists/linux/kernel/1058276?page=last

But for me - it started with 2.6.30-rc kernels.
I've T61, 4GB, C2D, X86_64.
