unfortunately, we don't fix firmware issues for these devices. Is the device unsupported? Or am I just in the wrong place (not a kernel bug)? I was following the instructions at http://wireless.kernel.org/en/users/Drivers/iwlwifi Also, the device is listed as currently supported for nuc's at http://www.intel.com/support/motherboards/desktop/sb/CS-033763.htm this device has driver support and not firmware support. You are not at the wrong place, it is just that unfortunately, Intel does not provide support for firmware bugs on these devices. Driver bugs will still be handled. Thanks -- I'll RMA the card. |
The best I can determine for reproducing this is that it seems to be related to large (1300+ byte, but under the link MTU of 1500) traffic and/or IPv6. Aside from the microcode errors, I'm seeing failures of IPv6 PTMU discovery (kernel seems to ignore ICMPv6 type 2 messages). iwlwifi 0000:02:00.0: Microcode SW error detected.
