configuring the iwl3945 module with disable_hw_scan=0 fixes the "speed
regression" problem for me on 3.0.0
but i still see the "Microcode SW error detected. Restarting
0x82000008." problem, in regular intervals, either 40 or 100 or 120
seconds
anyone still affected by the "speed regression", try adding the
parameters to a file under /etd/modprobe.d, eg:
# cat /etc/modprobe.d/iwl3945.conf
options iwl3945 disable_hw_scan=0
then, with (as root)
modprobe -r iwl3945
modprobe iwl3945
you can hope to better speed
if this helps for you, it would probably be helpful if you could post
success/failure here, and along the way i would also be interested is
someone sees these "Microcode SW error" issues
please also add the output of
lspci -vnn |grep -A3 Wireless
uname -a
lsb_release -rd
output on my machine:
