Getting message from syslog disabling irq16

dont_stop_me · 05-12-2008, 01:42 AM

Hi I'm getting a message at random occasions: syslog disabling irq16, after which the computer stops to respond. I'm using Slackware 12.1 but I had the same problem in Salckkware 12.0. I'm using the standard kernel, I have two SATA hard drives and one ata optical drive. Is there any way to avoid getting this message?

being random does not help but lets start at the bios

1) do you have your bios manual and have you set it to apic bios rather than pic?

2) if you have a modern bios it should allow auto setting for irqs and or set (change) irq x to y

linux

1) after booting pls run and post full results of

Code:

cat /proc/interrupts

2) your kernel can also make a difference as that supplies the drivers

the kernel should allow irq sharing

we can tell by your irq output thanks

my /proc/interrupts looks like this:

sorry for my late reply, i am making my thesis paper

dont_stop_me · 05-14-2008, 03:31 PM

oh, and I tried to modify my interrupts from bios but only interrupts from 1-15 can be assigned manually

aus9 · 05-14-2008, 07:11 PM

ok you are using apic irq bios system which is better than pic and irq 16 is shared which is ok but it enables libata which is normally a sata driver.

can you post your ide and sata drives to confirm pls

and that would explain why your drive locks up.

2) so could be bios or kernel IMHO

I copied what I thought would be useful from dmesg

slackware normally uses lilo.

try a new entry if you are using lilo....copy all the stuff but new entry titled
irq

the parameter I want you to use is
pci=routeirq

and a nice list of others if you want to experiement is
http://www.cyberciti.biz/howto/quest...parameters.php

yes my tip is not there heh heh.

2) so you try it and then run the cat proc command and see if you can get something like mine
cat /proc/interrupts
CPU0
0: 287 IO-APIC-edge timer
1: 1545 IO-APIC-edge i8042
3: 1 IO-APIC-edge
4: 1 IO-APIC-edge
6: 9 IO-APIC-edge floppy
9: 0 IO-APIC-fasteoi acpi
12: 49850 IO-APIC-edge i8042
14: 10044 IO-APIC-edge pata_via
15: 0 IO-APIC-edge pata_via
16: 122055 IO-APIC-fasteoi EMU10K1, nvidia
18: 6096 IO-APIC-fasteoi eth0
20: 141743 IO-APIC-fasteoi sata_via
21: 0 IO-APIC-fasteoi ehci_hcd:usb1, uhci_hcd:usb2, uhci_hcd:usb3, uhci_hcd:usb4, uhci_hcd:usb5
NMI: 0 Non-maskable interrupts
LOC: 973463 Local timer interrupts
RES: 0 Rescheduling interrupts
CAL: 0 function call interrupts
TLB: 0 TLB shootdowns
TRM: 0 Thermal event interrupts
SPU: 0 Spurious interrupts
ERR: 0
MIS: 0

and my syslog entry is of course
May 12 02:29:44 gs kernel: PCI: Routing PCI interrupts for all devices because "pci=routeirq" specified

of course I also use a vanilla kernel but that should not make a lot of diff to irqs

dont_stop_me · 05-16-2008, 04:33 AM

I tried the pci=routeirq kernel parameter, I didn't get any irq disabled so far. I guess problem solved. Thank you.
My /proc/interrupts looks now like this:

what distro?
what kernel?
what is your current bootcode or cheatcode?
show the line of of your syslog pls.

Note I am not a frequent poster here as I am having some browser issues using LQ

if I or others do not reply...post to your distro's forum as well pls
