Hello!
I recompiled recent RELENG_7 and I get the following panic after
trying to kldload if_nve (interesting stack frames are 12, 13, 14 I guess).
Previous version of RELENG_7 (compiled in the middle of December)
worked fine. Last few days I was trying to re-cvsup and always get the
same panic. I get FreeBSD sources via cvsup (cvsup5.freebsd.org).
Any suggestions?
Thanks in advance!
