Silicon Image drivers Problems with Mountain Lion
2009 MacPro with eSata card went through grief with the upgrade from Snow Leopard to Lion. But during the upgrade yesterday to Mountain Lion, the installer moved the kext file to the Incompatible Drivers folder and took my external multidrive box offline. Time machine restore back to 10.7 got me working again, but ... known working drivers should not be "killed" like that.
Anyone else see this issue?
