| |
Hello list,
There is a "ttyS1 irq is -1" problem observed on tiger4 which cause the serial port broken. It is because that there is __no__ ACPI IRQ resource assigned for the serial port. So the value of the IRQ for the port is never changed since it got initialized to -1. The attached patch falls back to the "no irq" hack for this case. It works for me. Please review and test.
Thanks, Luming
