Can you post the contents of /proc/interrupts with and without MSI enabled? (In reply to comment #2) > Can you post the contents of /proc/interrupts with and without MSI enabled? Sure, there you go. Created attachment 345690 [details]

Ping? ACPI: BIOS bug: multiple APIC/MADT found, using 0 ACPI: If "acpi_apic_instance=2" works better, notify linux-acpi.org Did you try acpi_apic_instance=2 ? Does the problem still happen without the binary nvidia driver? Sorry but none of those made any noticeable change, still multiple hangs on boot and awful disk speed... Let me know if I can be more useful (sorry but this is my very first experience at kernel debugging). Only three devices are using MSI. You can't blacklist the ahci driver but maybe you can blacklist the tg3 and iwlagn drivers. Just create a file in /etc/modprobe.d/ and put two lines in it: blacklist tg3 blacklist iwlagn Reboot with msi enabled and see if that works. If it does, try with only one line at a time. (You won't have a network connection while trying this.) I tried that too, but with no luck. Exactly same behaviour. The problem seems to lie in the ahci driver, isn't there a way to specifically force ahci not to use MSI? One further confirmation is that if I disable ahci mode from bios settings, thus booting in ide emulation mode, everything works just fine: no hangs, no slowdowns, no nothing.

No, but it has a very short blacklist for systems that are known to fail with MSI enabled. Can you post (as an attachment) the output of the command 'lspci -vnn' for your machine? Sure, done.

I don't know if any further action should be taken here, I just wanted to confirm that also the F11 kernel suffers from this problem, I couldn't even install without the pci=nomsi parameter. This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping I still see this bug in F11 and F12, changing it accordingly.

The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
