I have de-installed everything related to DRM and commented out the rc.conf statement that loads the DRM modules and still can't get past the last few steps of the startup. I did see that ntpd does read it's configuration file because my /var/log/messages has an entry for reading the leap seconds file. That is the last entry in the /var/log/messages file. I am able to successfully use the beadm choice 7 in the boot chooser to load a previously good boot environment working kernel. I'll try your other suggestions tomorrow morning and post the result to this group. Tom --=20 Public Keys: PGP KeyID =3D 0x5F22FDC1 GnuPG KeyID =3D 0x620836CF
