-Eric has reported on OpenWrt's bug tracking system[1], that he's not
-able to use USB devices on his WNDR3400v2 device after the boot, until
-he turns on GPIO #21 manually through sysfs.

-From: Jeff Hansen <jhansen@cardaccess-inc.com>
-Subject: [PATCH] no highpage
-
-On ASUS WL-500gP there are many unexpected "Segmentation fault"s that
-seem to be caused by a kernel. They can be avoided by:
-1) Disabling highpage
-2) Using flush_cache_mm in flush_cache_dup_mm
-
-For details see OpenWrt ticket #2035 https://dev.openwrt.org/ticket/2035

-Subject: [PATCH] ssb: reject PCI writes setting CardBus bridge resources
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-If SoC has a CardBus we can set resources of device at slot 1 only. It's
-impossigle to set bridge resources as it simply overwrites device 1
-configuration and usually results in Data bus error-s.
