ISDN AVM-B1-PCI / VT-d / System-Crash

[trendco]

Hi,

i have a big Problem with my ISDN-Card:

System: Proxmox-2.0-RC1
Board: Intel DQ67SW (VT-d activated)
PCI-Slot: AVM-B1-PCI
PCIe-Slot: DVB-Card (for Passthrough)
"intel_iommu=on" is activated in grub

For the AVM-B1 i installed "libcapi20" & "capiutils":

aptitude install libcapi20-3
aptitude install capiutils

Then i activated the Card in "/etc/isdn/capi.conf" and copied the Firmware "b1.t4" to "/lib/firmware/isdn"

After "capiinit start" the CAPI is active and "capiinfo" shows the correct Data.

But if i want to reboot the System or i try to stop the CAPI with "capiinit stop", the System crashes!

If "intel_iommu" is deactivated in grub, this error not happens. But i need this function for passthrough of my DVB-Card.

Has anyone a Idea?

...not sure how to detect this in linux, but for passthrough of a PCI ressource, you need to passthrough everything that is behind that particular pcie slot of the chipset.

I only want to passthrough the PCIe-Card, not the PCI !!

...actually either way might be bound to the same problem.
Make sure that the PCIe card is not attached/bound to a socket that is also the same resource of the PCI slot (where the PCI is listed behind that particular PCIe).
The PCIe and PCI slots need to have different root entries in the lspci output

The Problem is solved for me.

-> http://www.linkpool.de/projekte/projektelinux/fcusb2.html -> "Kernel Panic"

The Problem comes from "capiutils".

Solution/Workaround: disable "#$DAEMON stop" in "stop" & "reload" procedure in "/etc/init.d/capiutils"
