  No.

  The same hangup has occured.

  Thank you. I did the following.

# portsnap fetch
# portsnap update
# cd /usr/local/sys/modules/drm-current-kmod/linuxkpi/gplv2/include/linux
# vi pagevec.h
(comment out line 49)
# cd /usr/ports/graphics/drm-current-kmod
# make
# make deinstall
# make install
# reboot

But, it hangs up.
