Hi Max,

This morning's kernel panics during boot.  The only change I saw
during cvsup this morning was this commit.

The panic occurs just after printing the message about adding
additional ABI support for linux, if that means anything.  I
assume you are not seeing this panic?

Here is a snippet from the panic:

panic: assertion: mcl->mcl_refs > 1 in m_mclfree
