I am happy to report that we have been able to fix this problem. I just wanted to wait a day or two to be sure that it won't resurface again. The last steps we did were: 1) Upgrade SuperMicro SS5015M-T BIOS from version 1.1 to version 1.1a 2) Inclusion of 'debug.mpsafenet=0' into /boot/loader.conf suggested in this mailing list. I would guess that the step 2 was what really solved the problem.
