Hi,

thank you for your answer, but everything seems quite fine with
8-RELEASE except for this issue.
I tried to recompile without SMP or PREEMPTION options and also to apply
oleg_at_ 's patch at
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/netinet/ipfw/ip_dummynet.c?rev=1.5.2.2;content-type=text%2Fplain
committed on RELENG_8 with no luck.
Upgrading was fine, I can say that all has been installed cleanly.
Thank you,
regards,
