In comment #40, I mistakenly said "we reassign 80:01.0 to an address that is under PCI0, not PCI1." I had misread the address 0xfd00000000 as 0xfd000000, but it is actually 0xfd_0000_0000, which is just after the [mem 0x80000000-0xfcffffffff] range from amd_bus.c, and is not in any of the apertures of either PCI host bridge.
I also mis-typed the boot option in comment #41. The workaround should be "pci=use_crs" (not "pcie=use_crs"). I'm planning to merge this patch, which should fix the problem: http://lkml.kernel.org/r/20150616165543.9306.88230.stgit@bhelgaas- glaptop2.roam.corp.google.com If all goes well, this will appear in v4.2-rc1. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1033299 Title: Ubuntu 12.04 - no sound with VT8237A/VT8251 To manage notifications about this bug go to: https://bugs.launchpad.net/alsa-driver/+bug/1033299/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
