Error in buildkernel. Permission denien

Hi,

while compiling kernel I got:

x86 -> /usr/src/sys/x86/include
/usr/src/sys/dev/bhnd/tools/nvram_map_gen.sh
/usr/src/sys/dev/bhnd/nvram/nvram_map -h
bmake[4]: exec(/usr/src/sys/dev/bhnd/tools/nvram_map_gen.sh) failed
(Permission denied)
*** Error code 1

Stop.

I saw another thread with the same problem, so I checked my zfs mount
options for /usr/src and set it exec=on

Now I have

zroot/ROOT/default on / (zfs, local, noatime, nfsv4acls)
devfs on /dev (devfs, local, multilabel)
zroot/tmp on /tmp (zfs, local, noatime, nosuid, nfsv4acls)
zroot/usr/home on /usr/home (zfs, local, noatime, nfsv4acls)
zroot/usr/ports on /usr/ports (zfs, local, noatime, nosuid, nfsv4acls)
zroot/usr/src on /usr/src (zfs, local, noatime, nfsv4acls)
zroot/var/audit on /var/audit (zfs, local, noatime, noexec, nosuid, nfsv4acls)
zroot/var/crash on /var/crash (zfs, local, noatime, noexec, nosuid, nfsv4acls)
zroot/var/log on /var/log (zfs, local, noatime, noexec, nosuid, nfsv4acls)
zroot/var/mail on /var/mail (zfs, local, nfsv4acls)
zroot/var/tmp on /var/tmp (zfs, local, noatime, nosuid, nfsv4acls)

but still the same error
(already deleted my src, obj and svn new src)

Thank you
