3.6.11.9-rc1 stable review patch. If anyone has any objections, please let me know. ------------------ From: Tejun Heo <tj@xxxxxxxxxx> [ Upstream commit bb9696192826a7d9279caf872e95b41bc26c7eff ] sata_inic162x never reached a state where it's reliable enough for production use and data corruption is a relatively common occurrence. Make the driver generate warning about the issues and mark the Kconfig option as experimental. If the situation doesn't improve, we'd be better off making it depend on CONFIG_BROKEN. Let's wait for several cycles and see if the kernel message draws any attention.
