[asterisk-users] IRQ 0 on BRI card (B200E)

[Paulo Santos]

Hello list,

I'm having a problem with a BRI card, a B200E (PCI-e) card on an Intel
server with a riser that I'm guessing is what's making the problem.

The output of lspci -vvv is:

07:00.0 ISDN controller: Cologne Chip Designs GmbH ISDN network
Controller [HFC-4S] (rev 01)
	Subsystem: Cologne Chip Designs GmbH Device e884

	Kernel modules: hfcmulti

I've tried some combinations of pci=noacpi, noacpi, noapic, acpi=nopci
and some others. Doesn't seem to do anything, I still get "0 devices
registered" on dmesg.

OS: Debian Lenny, kernel 2.6.26.

Anyone has any idea of what I can do to fix/further debug this issue?

Thanks in advance.
Best regards,
Paulo Santos
