I write a quirk patch. Can you test?Yes, that makes it work !I just find one MCP51 and two MCP79 OHCI id. Can you provide more buggy hcd id via "lspci -nnvvv"? Thanks.I have the MCP61 (rev. A2) with id 10de:03f1. Further NVIDIA OHCI HCD IDs can be found at http://openbenchmarking.org/linux/PCI/0c03. But I'm not sure that we should blacklist them all. Maybe this bug has been fixed in newer chipset revisions / generations ? Where did you get the ID for the MCP79 from ? Is it confirmed that this device still suffers from the same bug ? I also wonder if this could be an BIOS / ACPI issue. So far, all boards I've seen were form ASUSTeK (Octavio: A8N-VM, me: M2N-VM DH, and I remember having seen the same bug on another M2N board with MCP55 a while ago).
These are 4 machines I found reported. I don't know what is the exact PCI ID needed, so I compiled links and information. MACHINE 1: DELL XPS 1340 Bug: https://bugzilla.kernel.org/show_bug.cgi?id=43081 The bug doesn't have system information, but a search on the Internet [1][2] suggest that it's an MCP79 chipset, integrated by Dell itself. [1] http://ubuntuforums.org/showthread.php?t=1927427 [2] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/969755 The lspci for [2] is at: https://launchpadlibrarian.net/99189829/Lspci.txt MACHINE 2 and 3: ASUS P4S8X and P4S8X-MX mainboards Bug: https://bugzilla.kernel.org/show_bug.cgi?id=47991 lspci: https://bugzilla.kernel.org/attachment.cgi?id=81331 Both are mostly unrelated to nVidia, except for the graphics card in one of them. Both have SiS-based chipsets. Enough device information in bug report. MACHINE 4: ASUS 1201N Bug: https://bugs.launchpad.net/linux/+bug/952080 lspci: https://launchpadlibrarian.net/96828581/Lspci.txt Also an nVidia MCP79-based device. All device info in bug report. -- Octavio.
