compiled jack 1.9.8 yesterday - didn't help. Now back on 1.9.7.

Yep.

Already is disabled.

Already done. They're both recognized and I know which hardware card
belongs to which device (always wondering after some time, so I check
that, first).

Already checked, now re-checked, it's ok.

You mean "lspci -v". There seems to be a silly situation:

lspci -v | grep IRQ -B2 output(shortened to relevant IRQs):

00:1d.2 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI
Controller #3 (rev 01)
        Subsystem: Foxconn International, Inc. Device 0c7e

	Subsystem: Foxconn International, Inc. Device 0c7e

So...SATA, USB and ICE1712 share one interrupt.
How can I change the interrupt of the devices, except by moving them to
another  slot? Though I'd really like to get rid of this, I can't
imagine, this is responsible for
Jack: JackGraphManager::AssertPort port_index = 4294967295
Looks like a dangling or uninitialized pointer to me.

I normally use QJackCtl, except for debugging this. QJackCtl froze and I
wasn't able to read the output. The command normally is:
/usr/bin/jackd -P89 -v -dalsa -r48000 -p256 -n4 -m -D -Cmulti_capture
-Pmulti_playback
but other frames/period, Priority etc. settings don't help.
I tried the settings from your page but without success.

Oh yes, I found the shared IRQs and I know for certain, it's possible to
use jack 1.9.7 with .asoundrc and two ICE1712.
Thank you!
