1.8b Development

Hey guys, after upgrading from 1.8.1b538 to 1.8.1b545 I began experiencing a boot loop almost religiously after serving the first dhcp lease (though I'm not positive that's the cause).  I suspected hardware as the last line on the console before the panic was "Root mount waiting for: usbus4" so I disabled all USB controllers on my Supermicro X7SLA and the problem stopped.  I then re-enabled USB and rolled back to b538 and things were fine again. Perhaps the additional SCSI and Network kernel modules mentioned in the release notes between the two builds are causing problems?  

Thanks for all your hard work on the 1.8 build!

I guess we can chalk it up to hardware, albeit coincidental! Replaced the PSU and everything is fine. 5V rail was putting out 4.7v and had lots of AC noise on it. Sorry for raising the noise floor here, but thanks again.
