  Thank you for reply.

  I updated to r352431 and this does not panic. Thank you very much.
  But 'make buildworld' fails by segment fault like below.
(buildworld is running over the nfs file system.)

--- modules-all ---
--- ath_hal_ar5211.ko.debug ---
objcopy --only-keep-debug ath_hal_ar5211.ko.full ath_hal_ar5211.ko.debug
Segmentation fault (core dumped)
*** [ath_hal_ar5211.ko.debug] Error code 139
make[4]: stopped in /usr/altlocal/freebsd-current/src/sys/modules/ath_hal_ar52111 error

  The position of segment fault is diffrent each time.
  The below is output of another 'make buildworld'.

--- kernel.full ---
Segmentation fault (core dumped)
*** [kernel.full] Error code 139
make[2]: stopped in /usr/altlocal/freebsd-current/obj/usr/altlocal/freebsd-current/src/amd64.amd64/sys/GENERIC

  /var/log/messages is shown as bellow.

  I can 'make buildworld' successfully on r351728(1300044).
