Re: Deadlock on 7.1
i experienced similar problems on my box:
Intel X38, 4gig ram, 2x 8600GT
The nvidia drivers refused to work, they eventually locked up my box on starting X.
A possible solution for this seems to remove some RAM (to get below/equal to the 3gig limit on i386) or some other trick i found somewhere on the freebsd mailing list archives:
Put this line in /boot/loader.conf:
I wonder why this is nowhere mentioned in the documentation/readme as it made everything work nicely even with 8gig of ram (despite of not having amd64..)
Hope this is helpful for you.
