-Subject: [PATCH FIX] brcmfmac: disable PCIe interrupts before bus reset
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Keeping interrupts on could result in brcmfmac freeing some resources
-and then IRQ handlers trying to use them. That was obviously a straight
-path for crashing a kernel.
-
-Example:
-CPU0                           CPU1
