Description of problem: I have random crashes since I upgraded from Fedora 11 to Fedora 12. I searched the internet to try to find the root cause of the problem. I think problems with interrupts sharing and MSI is the root cause. This link describes symptoms very similar to the ones I have (including a solution that I did not try yet): http://www.nvnews.net/vbulletin/showthread.php?t=148987 I expience often a kernel oops when I insert my Openmoko phone to a USB port. Sometimes, I noticed that a crash occured just after playing a sound. (This all indicates that it might be an interrupt issue in my opinion) How reproducible: I can not reliable reproduce the crashes. But when I plug my Openmoko phone to one of the USB ports, the crash occurs more often, both while booting or just randomly. It results also often in a kernel oops.

Could this be related to bug #564138?
I made some configuration changes: 1. added enable_msi=1 option to snd-hda-intel: cat /etc/modprobe.d/alsa-base.conf #options snd-hda-intel model=3stack-6ch options snd-hda-intel model=3stack-6ch enable_msi=1 2. added NVreg_EnableMSI=1 to nvidia: I created this file: cat /etc/modprobe.d/nvidia.conf options nvidia NVreg_EnableMSI=1 Now I have these interrupts: cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 0: 130 0 0 0 IO-APIC-edge timer 1: 2 0 0 0 IO-APIC-edge i8042 4: 2 0 0 0 IO-APIC-edge 7: 0 0 0 0 IO-APIC-edge parport0 8: 1 0 0 0 IO-APIC-edge rtc0 9: 0 0 0 0 IO-APIC-fasteoi acpi 14: 0 0 0 0 IO-APIC-edge ata_piix 15: 0 0 0 0 IO-APIC-edge ata_piix 16: 0 0 0 0 IO-APIC-fasteoi uhci_hcd:usb5 18: 0 0 0 0 IO-APIC-fasteoi uhci_hcd:usb4 19: 8349 0 51272 0 IO-APIC-fasteoi ata_piix, uhci_hcd:usb3 23: 8715 0 5114 0 IO-APIC-fasteoi ehci_hcd:usb1, uhci_hcd:usb2 27: 538 0 333 0 PCI-MSI-edge HDA Intel 28: 96 14598 0 2187 PCI-MSI-edge eth0 29: 298 0 476 0 PCI-MSI-edge nvidia NMI: 0 0 0 0 Non-maskable interrupts LOC: 322018 170226 244370 105919 Local timer interrupts SPU: 0 0 0 0 Spurious interrupts PMI: 0 0 0 0 Performance monitoring interrupts PND: 0 0 0 0 Performance pending work RES: 2434 1692 1591 1688 Rescheduling interrupts CAL: 12798 200 3783 234 Function call interrupts TLB: 1922 2152 3575 2108 TLB shootdowns TRM: 0 0 0 0 Thermal event interrupts THR: 0 0 0 0 Threshold APIC interrupts MCE: 0 0 0 0 Machine check exceptions MCP: 3 3 3 3 Machine check polls ERR: 3 MIS: 0 I will report later whether the stability of system increased.
Unfortunately, I experienced a system lock up during boot again.
Since I upgraded my FC11 to FC12, I am also experiencing lock-ups / system freezes. This is very annoying since the server is a critical machine in the network. On FC11, I never had even one lock-up. The only way to work around this that I found was to remove the kmod-nvidia drivers completely from the system and keep the "nomode" kernel parameter in grub.

To be clear: I also never had the crashes on Fedora 11. Recently I changed my bios settings to: PnP aware OS enabled. But I had a system hang after that again. However, the system crashes occur less frequently after enabling interupt sharing (MSI) for nvidia and nda-intel. Also, this bug #589007 may be related.

See http://forums.fedoraforum.org/showthread.php?t=245839 for similar problem on Fedora 13. With the same symptoms I have (now also on Fedora 13).

I removed the nvidia drivers, and I'm using nouveau now. The crashes still occur...
Yes, that also happened to me. I added "nomodeset" to the grub configuration's kernel parameter line. So far, the system seems to be running stable. Can you try that?
tried 'nomodeset' but this caused my system to boot in a very low resolution maybe 640x480. After manually selecting a standard LCD monitor with 1280x1024 the screen was garbled, but the items on the desktop were still kind of recognizable.
I updated the motherboard's bios to the latest bios version and this seems to help. I am running the system now with the standard xorg-x11-drv-nouveau with kms and it seems to be stable.
Eddie, what motherboard do you have? I have an Asus P5B-MX.
Intel moederbord 'Skyburg' BOXDP45SG/P45
Jan, Since the BIOS update I have not experienced any crashes anymore. It seems my problem is solved now. I hope something similar might work for you too? Regards, Eddie.
I updated my bios (now version 0704), but crashes still occur. See also this thread for similar problems: http://fedoraforum.org/forum/showthread.php?t=235793
Yesterday, I enabled 'PEG force x1' in my BIOS. No crashes since then.
Probably related to, or similar as bug #596330.
Copied here from now closed bug #589007: - The problems started for me after the upgrade to Fedora 12. - Fedora 11 was rock stable. - Fedora 13 still has the issue. - First, I thought it was nvidia driver related. Then I removed all nvidia stuff, and I'm using nouveau now, but the bug still is there. - Sometimes, my system runs for hours without a crash. - Sometimes, it hangs already during boot. - The more hardware is connected, the sooner the crash occurs (e.g. external disk, Openmoko phone, both via USB). - I have the impression that I have less frequent freezes after using MSI interrupts for my audio (and nvidia, when I was still using this driver). - I'm using an ASUS P5B-MX motherboard. - The system freezes without leaving any logging about errors. See comment #17 for my current work around, but I think that this will have a serious performance penalty.
This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. 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 '13'. 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 13'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 13 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
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 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.
