I'm having trouble getting a Sycard PCCHost 1420 (TI1420 chipset)
PCI-cardbus bridge working in a regular desktop PC (FC4, 2.6.14) using
the kernel supported module (yenta).  Here's what I'm seeing:

Yenta: CardBus bridge found at 0000:04:00.0 [0000:0000]
Yenta: Enabling burst memory read transactions
Yenta: Using CSCINT to route CSC interrupts to PCI
Yenta: Routing CardBus interrupts to PCI
Yenta TI: socket 0000:04:00.0, mfunc 0x00001000, devctl 0x66
Yenta TI: socket 0000:04:00.0 probing PCI interrupt failed, trying to
fix
Yenta TI: socket 0000:04:00.0 falling back to parallel PCI interrupts
Yenta TI: socket 0000:04:00.0 no PCI interrupts. Fish. Please report.
Yenta: no PCI IRQ, CardBus support disabled for this socket.
Yenta: check your BIOS CardBus, BIOS IRQ or ACPI settings.
Yenta: ISA IRQ mask 0x0000, PCI irq 0
Yenta: CardBus bridge found at 0000:04:00.1 [0000:0000]
Yenta: Using CSCINT to route CSC interrupts to PCI
Yenta: Routing CardBus interrupts to PCI
Yenta TI: socket 0000:04:00.1, mfunc 0x00001000, devctl 0x64
Yenta TI: socket 0000:04:00.1 probing PCI interrupt failed, trying to
fix
Yenta TI: socket 0000:04:00.1 no PCI interrupts. Fish. Please report.
Yenta: no PCI IRQ, CardBus support disabled for this socket.
Yenta: check your BIOS CardBus, BIOS IRQ or ACPI settings.
Yenta: ISA IRQ mask 0x0000, PCI irq 0

Here's my entire dmesg output:

I've been doing some searching and saw one person claimed to get around
this by using the reserve= boot parameter but I don't really understand
what it is I should reserve.  I've tried a couple other boot params -
yenta_socket.override_bios=1 and pci=routeirq - but neither made a
difference.  At the vendor's request I've also tried booting with a
PCMCIA card in one of the slots, also no difference.

Any pointers would be appreciated.

Thanks,

Nathan French
