Subject: [wireless-testing] iwl3945: ErrMsgs "MAC is in deep sleep!" and "mac80211-phy0: failed to set key" and unused variables in build-log
Date: Wed, 7 Jan 2009 12:01:27 +0100 [thread overview]
Message-ID: <2d0a357f0901070301ha31f71cma046bdc9590f0e33@mail.gmail.com> (raw)
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?
[2] Loading the driver with debug-options shows problems with
"mac80211-phy0: failed to set key":
# modprobe iwl3945 debug=0x43fff

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,
