Hello,
Thank you very much for your assistance.
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.
Best Regards
Daniel Ryslink

Because I can't reproduce it here and I failed to find a possible
cause of the issue.
As a last resort would you give attached patch a try?
The patch was generated against latest stable.
