Find IRQ conflict
location: ubuntuforums.com - date: September 26, 2010
I have an M-Audio Fast Track Pro (USB audio sound card) and I get a lot of clicks/pops even with high latency (44ms), even if I use M-Audio ASIO driver under Windows. I read that this problem could be due to an IRQ conflict, that is there are other hardware devices sharing the same IRQ channel.
How can I detect which hardware devices are sharing the M-Audio one?
IRQ Conflict nVidia and AHCI
location: ubuntuforums.com - date: January 8, 2009
I refer to the following thread: http://ubuntuforums.org/showthread.php?t=734106
I'm getting the exact same problem on my computer, although it only seems to be happening with a certain laptop (Asus G2S). In summary, nVidia and AHCI are sharing the same IRQ 16, and they sometimes argue with each other, bringing the whole system down.
The solution posted was to disable ahci, and use the ata_piix module instead, and at the same time switch the BIOS SATA mode from "Enhanced" to "Compatible".
I'm currently on Ubuntu 8.10 with kernel 2.6.27-9, and experiencing the same problems with nvidia-glx-177 and 173.
If I wish to disable ahci, must I recompile my kernel? Anyone on other platforms affected by this issue? If not, I fear that this problem may remain unfixed, as "Linux users on Asus G2S" seems like a small enough group.
pci usb irq conflict
location: linuxquestions.com - date: March 20, 2006
my usb bus is pci as hwconf and from dmesg i found both pci and usb-uhci has same irq 11. so if i insert a pendrive or any other usb device i always get
error -110. device does not take address=...
i tried to change usb-uhci irq by modprobe usb-uhci io=0xe400 irq=10
but it does not work and irq remain as just before 11.
the pci device 00:07.2 is the usb bus.
How can i change irq of usb or pci?
Crashing repeatedly, undiagnosed, possible IRQ conflict?
location: ubuntuforums.com - date: September 15, 2014
Symptom is the computer will do a full freeze/hang/crash.
CPU: Core i7 880
Mobo: EVGA 120-lf-e650
RAM: 8gb (4x2gb) 1333mhz
HDDs: 4x4tb, 2x3tb, 2x2tb, 120gb SSD for Ubuntu 14.04.1LTS all RAID 0
The mobo has 5 sata ports, have a 4 port sata PCIe x1 card for the other 4
I'm pretty new to Ubuntu/Linux. This crashing has been happening since changing over to Ubuntu 12.01LTS like 8 months ago.
Sometimes it can go a week without crashing, sometimes it's a few times a day. This is a Plex Media Server as well.
With googling I have discovered /proc/interrupts (I don't see anything obviously wrong)
I also have HardInfo installed (System Profiler and Benchmark).
I'm not too familiar with the log files, let me know what you want to see.

How view IRQ device list? how change default IRQ device? and how fix it ?
location: linuxquestions.com - date: September 28, 2003
I run dual boot Windows95/Linux Redhat 9 on a computer with a PnP Bios.
Under Linux there is an IRQ conflict between the serial mouse on COM1 and the PnP modem on COM3 where both want to use IRQ 4. There is no conflict under Windows, where the modem uses IRQ 10.
I would like to change the IRQ for either the mouse or the modem. I have tried using setserial to change IRQ for ttyS0 (mouse on COM1), but get an error message that the mouse is in use and so the IRQ cannot be changed.
Linux does not allow me to make changes to the file /proc/isapnp where the IRQ 4 is listed for the modem.
Please has anyone suggestions for resolving the conflict.
protential IRQ conflict ??? results of /proc/interrupts
location: linuxquestions.com - date: January 2, 2004
i was just catting /proc/interrputs today and receive following line:
11: 146141 XT-PIC eth0, nvidia
Does this mean my NIC is sharing the same IRQ # with my graphic card???? My computer works fine but this line just confuse the heck out of me. I am linux newbie, please advise.
Centos IRQ Conflict
location: linuxquestions.com - date: May 29, 2009
Ok so i have reached that point.... i have searched and googled but to no avail so i come to you guys. Basically i have a triple boot setup on a mac pro tower. windows /osx /centos 5.3 everything was great until i tried setting up my Wacom. I did get it setup but in the process revealed a problem i was having that i didn't notice until this point. Mind you my system boots perfectly everything runs perfectly except i belive my DVDrom and rear usb ports are trying to share the same IRQ.... and from what it looks like they don't want to play nice with each other. Eventually CentOS kills the IRQ thus killing both devices. everything works fine on the windows and mac osx side.
I have tried unpluging and repluging the DVDROM, I wanted to try another ide channel but the motherboard only has one. I have changed the device from auto to master to slave. When the DVDROM is removed i have no IRQ errors in my dmesg. I forgot to add that adding IRQpoll to my grub boot pretty much destroys the sys
IRQ conflict & ethernet configuration please
location: linuxquestions.com - date: October 7, 2001
Hi, I have 2 problems that have been plagueing me.
I am running Slackware 8.0 kernel 2.4.5
first, I am trying to get my sound card configured but am having a problem with an IRQ conflict, the following:
dmesg | grep IRQ
shows the following:
sb: Interrupt test on IRQ5 failed - probable IRQ conflict
eth0: ADMtek Cetaur-P rev 17 at 0xe400, 00:03:6d:10:E9:F2, IRQ5
eth1: VIA VT3043 Thine at 0xe800, 00:50:ba:04:37:83, IRQ 11
so I guess my question here is, how can I change the IRQ of etho to something other than 5 so that my sounc card will work correctly?
Also I am having problems getting my machine w/multiple NIC's configured.
The 2 NIC's are:
D-Link DFE=530TX PCI Fast Ethernet Adapter
Network Everywhere Fast Ethernet (NC100 V2)
ifconfig shows eth0 and the card that the is working is the NE (NC100 V2) but the D-Link is not being seen on reboot.
ifconfig -a shows eth0 & eth1.
I have tried uncommenting the following in /etc/rc.d/rc.modules
IRQ / interrupt conflict issues with megaraid and Linux SOLVED
location: linuxquestions.com - date: February 3, 2010
Ever since Linux kernels beyond 184.108.40.206, I've been unable to boot my HP Netserver LH3.
It gives a kernel panic with a variety of messages that always include "common_interrupt+0x38/0x39"
I tried everything from updating the BIOS and firmware, to myriads of differing kernel configurations (at 4 hours per compile, imagine the agony).
I also tried booting with every combination of the kernel boot parameters acpi=off, noapic, nolapic, irqpoll, etc that I could imagine. No dice.
In final desperation, I began unplugging PCI cards one by one before finally disconnecting the SDLT drive from the Netraid SCSI. Et voila!
It seems that in later kernels or versions of udev, sharing the SCSI bus with the LH3 drives causes conflicts.
I have an additional AHA SCSI card in the machine, so will try connecting the SDLT to that and see how it goes.
