Public bug reported:
When I attempt to transfer large files over the Intel WiFi 4965 card in
my Dell Vostro 1500 laptop running Kubuntu Jaunty 64, I have problems
with Microcode SW errors. I get the error either after the wireless
card has transferred 1.5GB of data, or if I turn the display on my
laptop off by any method. I have reproduced both of these actions a
number of times each, using the regular iwlagn driver and the linux-
backports-modules driver. I never get this error unless I do try to
transfer more that 1.5gb of data (in one large file, not many little
ones) over the local network, or I close the lid while transferring such
a file.
Here is the error I get:
[ 286.265729] iwlagn: Microcode SW error detected. Restarting 0x2000000.
[ 289.236173] iwlagn: Can't stop Rx DMA.

[ 289.943615] Registered led device: iwl-phy0:assoc
[ 289.943663] Registered led device: iwl-phy0:RX
[ 289.943698] Registered led device: iwl-phy0:TX
Loading the module with debug=0x43fff produces the exact same output
when the problem occurs. The error also occurs no matter whether I am
receiving or transmitting the file from my laptop.
Here is the card's output in lspci:
