I try, but with the wold of 7.1-PRERELEASE I got

cc: Internal error: Segmentation fault: 11 (program ld)
Please submit a full bug report.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
*** Error code 1

Stop in /usr/obj/usr/src/sys/MORZINE.
*** Error code 1

Stop in /usr/src.
*** Error code 1

Stop in /usr/src.

So I get /usr/bin/cc /usr/bin/ld /usr/libexec/cc* from a previous
7.0-STABLE and try it again... with a lot of cpu-system... >80% on a
dual core.

Anyway - I reboot the new kernel without KDTRACE_HOOKS and DDB_CTF.

After reboot, system cpu is always very high and system not responsive.
