    Hello,

    i tried 2.6.0-test on a laptop (Sony Vaio FX502, AMD Mobile Duron
    1GHz)

    With a PCMCIA-Modem (ELSA Microlink 56k MC Internet, a V.90 Modem) I
    have only 1/3 throughput with 2.6.0-test4 compared to a 2.4.X kernel
    (which gives the normal throughput for 56k modem).

         Yenta: CardBus bridge found at 0000:00:0a.0 [104d:80f6]
         Yenta IRQ list 0008, PCI irq11
         Socket status: 30000010
         Yenta: CardBus bridge found at 0000:00:0a.1 [104d:80f6]
         Yenta IRQ list 0008, PCI irq10
         Socket status: 30000006
         cs: memory probe 0x0c0000-0x0fffff: excluding 0xc0000-0xd3fff 0xdc000-0xdffff 0xe4000-0xfffff
         serial_cs: RequestIRQ: Unsupported mode
         ttyS1 at I/O 0x2f8 (irq = 0) is a 16550A
         ...
         ttyS1: 1 input overrun(s)

    pulling the card out I get

         Trying to free nonexistent resource <000002f8-000002ff>

    pushing it in again I get:

         serial_cs: RequestIRQ: Unsupported mode
         ttyS1 at I/O 0x2f8 (irq = 0) is a 16550A

    lspci says:
         00:0a.0 CardBus bridge: Texas Instruments PCI1420
         00:0a.1 CardBus bridge: Texas Instruments PCI1420

    So it seems the card is not getting an interrupt with 2.6.0-test4 for
    some reason I don't understand.

    BTW: 'serial_cs' has been renamed to '8250-cs' but there are still
    references to 'serial_cs' in source, messages, Kconfig ("The module
    will be called serial_cs.") and Documentation.

    I'm not on kernel-mailing-list.
