What hardware do you have? It would be helpful if you could provide more details, please give the output of
sudo lspci -v
assuming it is some kind of compatibility issue.
Also, does the computer completely freeze when this happens (kernel panic) ? Can you do Ctrl+Alt+F1 to change to a TTY for instance. Do the SysRq (key on print screen) shortcuts work (hold down Alt and Sysrq, then press and release the following: R E I S U B). If the system reboots, the freeze can't be too severe.

You could also try booting with different options (entered by pressing 'e' on grub) - you could try adding 'text' after 'quiet splash', to see if text mode boots ok. Adding 'acpi=off' may also be an option to disable power management.

Do you have any proprietary graphics drivers (e.g. NVIDIA/ATI) - these may be a possible cause also.

Hope we can sort this issue out
