Hi, there are several reports of Xonar PCIe sound cards failing to work in kernel 4.4 (including 4.4.5):
https://bugzilla.redhat.com/show_bug.cgi?id=1313790 https://bugzilla.kernel.org/show_bug.cgi?id=111711 https://bbs.archlinux.org/viewtopic.php?pid=1601338#p1601338 They show error messages like this: AMD-Vi: Event logged [IO_PAGE_FAULT device=03:00.0 domain=0x0000 address=0x000000000020cf00 flags=0x0070] All these cards use a PCI chip, with different PCIe bridges (ASM1083, PEX8112, PEX8111). It probably matters that "03" is the PCI bus, but that device "00" does not exist.
