Hi Tejun, below are two things in ahci I found while converting the driver to the new MSI / MSI-X vector allocator. The first one looks like an obvious bug to me if we every have these stray ports in a per-port IRQ vector setup. The others one is more elaborate, but I think the per-port locking is something we should do for the per-port MSI-X case just like for the per-port MSI case. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
