#23372: kernel panic if CONFIG_USE_MKLIBS is set (mipsel target)
 Reporter:  pmrbpmrb  |      Owner:  developers
     Type:  defect    |     Status:  new
 Priority:  normal    |  Milestone:
Component:  kernel    |    Version:  Trunk
 Keywords:            |

 When CONFIG_USE_MKLIBS is set (Strip unnecessary functions from
 libraries), then the kernel panics on my board.

 Steps to reproduce:
 - git clone ​git://github.com/openwrt/openwrt.git
 - cd openwrt
 - make menuconfig
   - Target System -> Broadcom BCM47xx/53xx (MIPS)
   - Target Profile -> ASUS WL-500g Premium v1 (Atheros WiFi using ath5k)
   - Global build settings -> Strip unnecessary functions from libraries ->
 - make
 - flash the device

 Here the output from the serial interface:
