Disabling IRQ #17


Hi
Im new to Linux
I have Slackware 12

After leaving my computer unattended for a while,I get the following message:
Kernel : Disabled IRQ #17

I also lose my internet connection. It seems my connection to my router gets disconnected.

I use DHCP to connect to the router.
I try to reconnect via
Code:
ifconfig eth1 down
ifconfig eth1 up
dhcpcd eth1
However, I am not able to reconnect. I end up rebooting my box inorder to reconnect.


Two questions:
1. What is IRQ #17??
2. How do I reconnect to the internet without having to reboot?

Thanks
okos

first of all, eth1 implies that you have two cards... is this a wireless card that is giving you issues? if so, what card?


assuming that eth1 is the correct interface, the commands you are typing *should* work.

More research on how to disable whatever is creating an irq confilct may be nessesary.

IRQ = interrupt request, i.e. a message from a device to the CPU signaling that the device in question needs attention from the CPU. Because the CPU needs to know where the message originated, IRQs are numbered. In modern computers (with PCI), one IRQ number can be shared among two or more devices, usually without any problem.

When an IRQ gets disabled, you won't be able (afaik) to use the device until you reboot.

Run dmesg or check your logs to find out which device(s) have IRQ17. Maybe it is the network card but it could just as well be something else that is sharing IRQ17 with.

Hi jay ,
I think there is a problem with my conextant software modem.
ACPI: PCI Interrupt 0000:00:1f.6[B] -> GSI 17 (level, low) -> IRQ 17

I suggest that you have a look at /cat/proc/interrupts to find out whether that is the whole story - although ti does look like it is. You could always try adding acpi=noirq or irqpoll to your kernel line in /boot/grub/menu.lst.
