I see two problems in the initial report from FichdlMaa: 1) Linux ignores ACPI _CRS information and consequently assigns addresses to the 80:01.0 device that may not work. 2) The page fault: "BUG: unable to handle kernel paging request at ffffc90000378000"
Booting with "pci=use_crs" should work around the first problem. This is only a workaround, not a real fix because we don't expect users to have to use that option. If "pci=use_crs" makes a difference, and if it still fixes a problem in the current upstream kernel (v4.0-rcX), please open a bug report at http://bugzilla.kernel.org (in drivers/pci category), attaching a complete dmesg log, and we can add a quirk to turn on that option automatically. I don't have a theory about the page fault problem. Details about the _CRS problem: bus: 00 index 2 [mem 0x80000000-0xfcffffffff] The range above is from amd_bus.c. Note that it covers the mem windows for both PCI0 and PCI1 below. PCI: Ignoring host bridge windows from ACPI; if necessary, use "pci=use_crs" and report a bug ACPI: PCI Root Bridge [PCI0] (domain 0000 [bus 00-7f]) pci_root PNP0A08:00: host bridge window [mem 0x80000000-0xbfefffff] (ignored) pci_root PNP0A08:00: host bridge window [mem 0xc0000000-0xdfffffff] (ignored) pci_root PNP0A08:00: host bridge window [mem 0xf0000000-0xfebfffff] (ignored) ACPI: PCI Root Bridge [PCI1] (domain 0000 [bus 80-ff]) pci_root PNP0A08:01: host bridge window [mem 0x000a0000-0x000bffff] (ignored) pci_root PNP0A08:01: host bridge window [mem 0xbff00000-0xbfffffff] (ignored) pci 0000:80:01.0: [1106:3288] type 0 class 0x000403 pci 0000:80:01.0: reg 10: [mem 0xbfffc000-0xbfffffff 64bit] The initial configuration from BIOS (above) looks correct. The 80:01.0 BAR 0 is inside the PCI1 host bridge window reported by ACPI _CRS. pci 0000:80:01.0: address space collision: [mem 0xbfffc000-0xbfffffff 64bit] conflicts with PCI Bus #00 [mem 0x80000000-0xfcffffffff] pci 0000:80:01.0: BAR 0: assigned [mem 0xfd00000000-0xfd00003fff 64bit] But we're ignoring _CRS and using the information from amd_bus.c, so we think there's a conflict with the PCI0 window. We reassign 80:01.0 to an address that is under PCI0, not PCI1. If the ACPI _CRS description is correct, this means MMIO accesses intended for 80:01.0 will never reach the device. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1033299 Title: Ubuntu 12.04 - no sound with VT8237A/VT8251 Status in ALSA driver: New Status in alsa-driver package in Ubuntu: Confirmed Status in alsa-driver-1.0.25-dkms package in Ubuntu: Confirmed Bug description: (3.2.0-27-generic #43-Ubuntu SMP Fri Jul 6 14:25:57 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux) [ 0.000000] DMI: Foxconn OEM/K8M890-8237A, BIOS 6.00 PG 02/10/2007 !!!
