The first step is done. The affected hardware doesn't boot from official 12.0-RELEASE CD either. Loader also freezes at the stage of loading kernel modules. These servers are old Maxdata Platinum 500 and 3200. Some time ago I have submitted dmesgs to NYC BUG dmesg repository[1][2]. Both configurations are fine with 11-STABLE, so I am not going to upgrade them and I am replying only FYI.
