Ok, I see some IRQ issues but not sure if this is the one causing the hangs. Typically some hangs are related to a physical issue (CPU, Memory....). If possible try moving the
3Ware to another slot closer to the CPU.

Then I want you to go back in to the console tools and then boot options.
Then select Boot Parameters and select all 3 options. Then reboot.

Also update to the latest version 5_0_47_build_3200 but you may have done so already.
