 |
|
hello,
a short intro: I have this nice new laptop and need to use a analog modem connection from time to time. since the internal modem is a winmodem I did a little dig and found it supported by the linuxant driver - but as you may know the driver is not for free (20$ I think). now I thought myself smart and got me a new pcmcia modem for only 5$ 
as I had only good experiences with pcmcia before I'm a little helpless now. here comes my problem:
everything seems to run just fine - the socket driver is ok - the card is recogniced - but then:
| Code: | Yenta: CardBus bridge found at 0000:02:04.0 [103c:30b0]
Yenta: Enabling burst memory read transactions
Yenta: Using INTVAL to route CSC interrupts to PCI
Yenta: Routing CardBus interrupts to PCI
Yenta TI: socket 0000:02:04.0, mfunc 0x01a11002, devctl 0x64
Yenta: ISA IRQ mask 0x0ef8, PCI irq 16
Socket status: 30000410
Yenta: Raising subordinate bus# of parent bus (#02) from #03 to #06
pcmcia: parent PCI bridge I/O window: 0x1000 - 0x1fff
pcmcia: parent PCI bridge Memory window: 0xd0000000 - 0xd02fffff
pcmcia: parent PCI bridge Memory window: 0x30000000 - 0x31ffffff
pccard: PCMCIA card inserted into slot 0
cs: memory probe 0x30000000-0x31ffffff: excluding 0x30000000-0x31ffffff
cs: memory probe 0xd0000000-0xd02fffff: excluding 0xd0000000-0xd002ffff
pcmcia: registering new device pcmcia0.0
pcmcia: request for exclusive IRQ could not be fulfilled.
pcmcia: the driver needs updating to supported shared IRQ lines.
0.0: ttyS0 at I/O 0x13f8 (irq = 16) is a 16550A

I did some research on this - it did not yield much but

this is exactly the same problem - but no solution 
any hints? what may I try?
thanks in advance for your help

After long hours of fiddling around I came to the only possible conclusion -> drop the hi-tech stuff and use pcmcia-cs.
And it works...
