>Description:
I did a binary upgrade from FreeBSD 6.4 (i386) to FreeBSD 7.3 using 'freebsd-update'. Everything is working fine except bridge().

Fortunetly, I don't manage the machine via the bridge0 interface. If I did, the remote upgrade would have cut me off and no longer let me ssh to it again. ...hence the Serious severity.


The problem is simply that the file /root/kernel/bridgestp.ko is missing on the upgraded system. When ifconfig try to create bridge0, the kernel module if_bridge.ko is loaded and when it in turn try to load bridgestp.ko, dmesg say:
"KLD if_bridge.ko: depends on bridgestp - not available"



On another FreeBSD 7.3 machine, installed as 7.3 directly from CD, the file /root/kernel/bridgestp.ko is present and bridge0 can be created. The problem only seem to exist when performing a major upgrade. (Note: I have only tested a binary upgrade, not the "build world" approach)


On the upgraded 7.3 machine I've run freebsd-update in IDS-mode. It didn't complain about any /boot/kernel/* files at all.
The upgrade itself didn't log any errors.

>How-To-Repeat:
Upgrade a 6.4 system to 7.x.
'/usr/sbin/freebsd-update -r 7.3-RELEASE upgrade'
