[Bug 136836] Re: Ethernet (nVidia MCP55) not working [ gutsy, hardy]
I agree that a mechanism for detecting functionality with different values would be superior to the quirk workaround. I added that on the assumption that this was a one-time problem which was caused by a BIOS bug on the Asus P5N32-SLI Premium. Since different potentially related occurrences have surfaced since that, I definitely think that this should be looked into. -- Ethernet (nVidia MCP55) not working [ gutsy, hardy] https://bugs.launchpad.net/bugs/136836 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 136836] Re: Ethernet (nVidia MCP55) not working [ gutsy, hardy]
After looking into the problem, I'm convinced that my problem (with the P5N32-SLI Premium mobo), is caused by a buggy BIOS. I also have the same PCI bridge and NIC on another Asus motherboard, where it works flawlessly (for small and large data transfers). I have submitted a kernel patch where msi is turned off as default for the P5N32-SLI Premium. The difference in behaviour suggests that the issue of theP5N- MX mobo is different from the P5N32-SLI Premium issue. Sadly, I cannot try to test and debug it since I don't have it. My advice is to submit this issue as a new bug. -- Ethernet (nVidia MCP55) not working [ gutsy, hardy] https://bugs.launchpad.net/bugs/136836 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks for the feedback. I'm primarily trying to find out if this is P5N32-SLI-specific, so a clarification of the above question is: Are there anybody (in addition to me) who still experiences the network problems after upgrading to 2.6.27+ and has other motherboards than the Asus P5N32-SLI Premium? -- Ethernet (nVidia MCP55) not working [ gutsy, hardy] https://bugs.launchpad.net/bugs/136836 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I got no suggestions/feedback when posting this question on the netdev- list, but I have done some experimenting with msi disabling for affected devices in order to produce a (preliminary) patch. What I would like to know is if there are other motherboards than the Asus P5N32-SLI Premium which are affected by this. I also would like to know if any of you have the Asus P5N32-SLI motherboard with other, working msi-enabled devices (to find out if this may be a global msi problem or limited to the MCP55-NIC). You can find out if a device has active msi by doing 'cat /proc/interrupts'. An "IO_APIC" is a pin-signalled device, while "PCI-MSI" represents msi-enabled devices. -- Ethernet (nVidia MCP55) not working [ gutsy, hardy] https://bugs.launchpad.net/bugs/136836 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've tested the current development kernel (2.6.28-rc3) on my computer (Asus P5N32-SLI Premium motherboard), and the problem is still present. I can take this to the mailing lists to try to find a reasonable solution. -- Ethernet (nVidia MCP55) not working [ gutsy, hardy] https://bugs.launchpad.net/bugs/136836 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
