I have two FreeBSD 9.1-amd64 virtual machines running on two different CPUs using Parallels
- Intel(R) Core(TM)2 Duo CPU P7350 @ 2.00GHz (13-inch Macbook Late 2008)
- Intel(R) Core(TM) i7-2635QM CPU @ 2.00GHz (15-inch Macbook Pro, Early 2011)
The Core 2 Duo runs CCL-1.8 fine, but the Core i7 has the same problem as Cyrille reported.
The Core 2 Duo does not have AVX extensions , but the Core i7 does have them .
The CPU information was obtained using:
sysctl -n machdep.cpu.brand_string
CCL-1.8 was obtained using FreeBSD ports.
