[Bug 1119678] Re: 8086:088e [System76 gazp7] iwlwifi: Microcode SW error detected
OK tested with upstream kernel 3.11.0-031100rc5.201308112135 and with
current lts-quantal kernel 3.5.0-37.58~precise1 and I still see this
issue.
Interestingly I get this with one AP that I regularly use, but not two
others that I use. The AP in question has an Atheros AR92xx radio, the
others (which don't seem to trigger this problem) are a Cisco SOHO
router (innards unknown) and a Mikrotik with Atheros AR9380 radio.

Title:
8086:088e [System76 gazp7] iwlwifi: Microcode SW error detected
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
This smells like bug #1099487 but is on a Precise kernel
(3.2.0-37-generic #58) rather than a Quantal 3.5 kernel.
I get this on boot now, possibly since updating to -37.
The system is a System76 gazp7 laptop (Core i7-3720QM according to
/proc/cpuinfo) with an Intel Centrino Advanced-N 6235 wifi adapter
(according to lspci)
