Ok, this is the workaround that got my SansungX11 intel laptop fix
(after a long battle):

First off what Phil recommended:
Adding the  "combined_mode=libata" option to the kernel boot line,
in the same way, add the following line to the /etc/modprobe.conf file:
options libata atapi_enabled=1
And then as surprising as it may seem, insert a cd or a dvd on your rom and leave it there. 
Now, I don't have any freezes .... can you believe it !
Here is my parameters for kernel line :
noapic nolapic clocksource=acpi_pm quiet
combined_mode=libata  atapi_enabled=1
I know is not ideal but I spend months on this issue an finally my laptop doesn't freeze ever! 
No more  kernel: ata1.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen!

-- 
Random freezes with "exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2" error
