Hello, I am running Arch Linux on a Macbook Pro 12,1 Retina (Early 2015) and get kernel oopses related to the brcmfmac module. The oopses occur when I am downloading multiple files from the internet, e.g. when running "git clone git://git.kernel.org/..." or"pacman -Syu". The problem occured on vanilla kernels 3.19.3 and 4.0.1 and on distro kernels 3.19.3-3 and 4.0.1-1. The access point the notebook is connected to is a FRITZ!Box 6340 Cable, running on channel 6 in the 2.4 GHz band. I am running wpa_supplicant and NetworkManager (nm-applet). Please find following the output of "lspci -vvnn | grep -A 60 Network" and the oops message while running the following command on kernel vanilla kernel 4.0.1: "git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git" ------------------------------------------------------------------------- lspci -vvnn | grep -A 60 Network ------------------------------------------------------------------------- 03:00.0 Network controller [0280]: Broadcom Corporation BCM43602 802.11ac Wireless LAN SoC [14e4:43ba] (rev 01) Subsystem: Apple Inc.
