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.
