The following lines from your dmesg output:
> eth0: 3Com 3CCFE575 Cyclone CardBus at 0x400, 00:10:4b:f1:78:b1, IRQ 11
> 3c589_cs: RequestIRQ: Resource in use
make it appear as if the card manager is trying to grab
IRQ11 for your card, whereas IRQ11 is required for the
PCI controller (and thus for USB and PCMCIA controllers).
I think you have simply run out of free interrupt lines:
0 timer
1 keyboard
2 IRQ controller cascade
3 IR
4 serial
5 sound
6 floppy controller
7 parallel
8 real time clock
9 575 Ethernet
10 sound
11 PCI controller: USB, PCMCIA controller
12 PS/2 mouse
13 math co-processor exception
14 primary IDE controller (for hard drive)
15 secondary IDE controller (for drive in the UltraSlimBay)
Why don't you remove the 575 and use the 556 for both
Ethernet and modem?
If you really need an additional IRQ then you might want to
disable the MIDI interface to your sound hardware and
use its IRQ.
