I just needed to about any issues that are seen with Gigabyte GA-M57SLI-S4 motherboard (are they serious?). The Supported motherboard(page of LinuxBIOS) lists this board but with yellow flag and code (WIP). I would like to know in particular what are the troubling issues with it.

Also if some one can suggest me a supported High end Desktop motherboard(with socketed BIOS), I would really be obliged.
