It always happens after the first bootup after upgrading the kernel an= d world This problem is not going away and appears to be getting worse.. Now we are seeing a similar problem after boot but the kernel panics! The panic is "panic: free: guard1 fail @ 0x51984 from /usr/src/sys/boot/i386/loader../../common/module.c:967" Can anyone shed some light on what is going on and things that I can do to prevent these problems? We would like to release pfSense (www.pfsense.com) around the same time that FreeBSD 6 releases but I'm affraid that with these problems lurking its not a good idea from a support perspective. Thanks again in advance! Scott
