Hi,
with wireless-testing master-2009-01-06 I discovered some problems
with iwl3945-driver.
[1] While unloading the driver with modprobe I got the following
error-message "MAC is in deep sleep!":
# modprobe -r -v iwl3945

Q: What does this mean in general "MAC is in deep sleep!"? Has this
something to do with power-management?

Are these issues known? gcc-4.4-related?
My Internet access is so far OK (see below).
Just reporting - If there is a fix let me know.
Kind Regards,

We are aware of this problem (see
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1834 ) and
are working on a fix for 3945.
I'll look into the build warnings - than you for the report.
