--- Comment #1 from kra...@gmail.com ---
I am getting regular kernel panics when I do transparent web interception with
squid and pf. I am unsure of whether this is an issue with squid or the pf
kernel module
Here is the kernel backtrace

I updated the kernel to the latest a few days ago but it still happens. Squid
is also the latest version in ports
