I looked at it few months back and found out that PCI initialization happens much too late for a serial console. It would take quite a bit of work to get serial console working on PCI cards. PA-Linux faced the same problem but they were able to get around it by using the firmware calls to do console I/O. If serial console were working on PCI serial cards, you wouldn't need ACPI to use it. -- Khalid ==================================================================== Khalid Aziz Linux Systems Operation R&D (970)898-9214 Hewlett-Packard khalid@fc.hp.com Fort Collins, CO - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
