6.2-RC1 em(4) issue - freezes during CD boot

[Chris Buechler]

I'm attempting to install 6.2-RC1 on a box that ran 5.3, 5.4, 6.0, and 
6.1 for the past few years, but the 6.2-RC1 CD won't boot.  After it 
detects the em0 NIC, before it gets into sysinstall, it freezes solid.  
I've let it sit there for over an hour. 

I know there has been some recent work on em(4), but it doesn't appear 
all the issues are resolved.  I'm not sure what I should try, what 
information I could provide that might be useful, etc.  I'd be more than 
happy to help troubleshoot this, with some guidance on what I could do 
to be helpful. 

Cheers,
-Chris
