Hello,
since an upgrade from Debian lenny, which was running on our
Dell-Server since 2009, we are now having problems with the
Passthrough of an PCI-USB-Controller which shares its IRQ 11 with 2
other PCI-Devices.
A PCI-Device whichs IRQ 35 is not shared can be attached to the
guest and works perfectly. This new behavior with the IRQ-shared
USB-Controller has begun after the update of DomO and DomU to Debian
squeeze/stable. The former configuration was:
DomO:
Kernel: 2.6.26-2-xen-amd64 (2.6.26-26lenny1)
Xen-Hypervisor: 3.2-1-amd64 (3.2.1-2)
DomU:
Kernel: linux-image-2.6.26-2-xen-686 (2.6.26-26lenny3)
Running DomU with the the old 2.6.26 Kernel doesn't solve the
problem. Running DomO with the old configuration would be a greater
downgrade because of incompatibilities between drbd-modules and
drbd-userlevel tools, which needs old lenny archives.
The actual Xen running now is from Debian's stable squeeze
release with DomO and DomU Kernel 2.6.32-5-xen:
DomO:

(the guest DomU is running at this moment, but the PCI-Device is not
attached yet. The upper output of "xm dmesg" does not change between
xen with no running guest
and starting a single guest)
As you can see from the DomO's Kernel-parameter "xen-pciback.hide=(00:03.0)"
the PCI Device to be passed through has the ID 00:03.0 .
An extract from # lspci -vv on DomO shows this Device with the

A bit strange is the difference between the triggers of IRQ 11
(level in xm dmesg, egde in /proc/interrupts):
in xm dmesg:
(XEN) Guest interrupt information:

while the triggers for IRQ 35 of the working SAS-Controllers look
like:
in xen dmesg

There is also a difference between the kinds of interrups between
IRQ 11 and IRQ 35.
Does someone have an idea how to fix this?
Kind regards,
