Hi.

I have one FreeBSD 9.1-STABLE which hangs often, and I suspect the pf. 
This sure looks like on of those posts 'I did something wrong but I will 
blame FreeBSD' but the thing is that I have a couple of open pr's that 
concern this machine and this particular pf configuration.
So, the thing is - it hangs, and I want to narrow it down. To some panic 
may be, or at least to some console message. Right now it hangs 
completely and silently, I cannot even enter the kernel debugger. It 
complains about nothing, I've already checked the memory with memtest86+ 
(two days and no errors) and installed a bunch of fresh firmwares (this 
is IBM system x3560). The period between lockups decreased a lot after I 
added some altq'ing, so... it may be pf or it may be not.

I will be really glad to hear some idead about how to debug the pf or 
about how to narrow the cause in general.

Thanks.
Eugene.
