[ltp] Two PCMCIA cards == conflict ?

[Torbjorn Tornkvist]

Hi ! 

I've got two PCMCIA cards:

 3Com Megahertz 10/100 LAN Cardbus
 3Com Megahertz 56K Modem

They work perfectly one at a time but when I
have both of them plugged in at the same time
I get some sort of conflict:

tty00 at 0x03f8 (irq = 0) is a 16550A
------------------------------------------------------------------------

Only the ethernet card now works. 
What does this mean:

 serial_cs: RequestIRQ: Resource in use

If the Ethernet card is not used, then the last line 
above looks like:

 tty00 at 0x03f8 (irq = 3) is a 16550A

From Windows I can see the the Ethernet card uses IRQ 11
and the Modem card uses IRQ 3.

Has anyone got a similar setup to work ?

Thanx /Tobbe
