[SOLVED] Slackware64-14.1 Syslog Disabling IRQ #16

Plutonium · 01-09-2014, 02:02 AM

Hey.
I have a very disturbing problem that affecting my network speed significantly, it's very slow.
I got this error after a bit of workingtime with the computer, sometimes right after a boot or a couple of hours.

Setup:
Slackware64-14.1 (UEFI) right out the box with 3.10.17 huge kernel

Log's:

Code:

have you tried passing that to the kernel at boot?

Plutonium · 01-09-2014, 03:38 AM

No I haven't.. How do I do that with elilo? I'm not at all familiar with this uefi stuff.

jtsn · 01-09-2014, 05:25 AM

PCI device 00:16.0 doesn't have anything to do with IRQ 16.

Most likely the semi-broken r8169 kernel module is causing the issue. That's why your network speed is bad. Try blacklisting it and replace it with r8168 version 8.037.00 available at

http://www.realtek.com.tw/downloads/...etDown=false#2

RTL 8168/8111 is a very common desktop NIC, but kernel developers don't care for desktops anymore, because in servers you usually find Intel NICs.

it's just like with lilo.
When you start the computer and get to the elilo screen, press "Tab" on the keyboard to get a list of the available kernel labels: by default you should have a "Linux" label.
Then simply digit the label name and the kernel parameters to apply on the fly, like

Code:

Linux irqpoll

and press enter to boot the kernel.

I would agree that the r8169 driver module is the cause. You could try a newer kernel in case they fixed it.

Plutonium · 01-11-2014, 05:31 AM

Thanks for the support!
Seems that irqpoll option did the trick.

Plutonium · 02-07-2014, 04:34 PM

Hi again.
Thanks again for the advice last time, irqpoll did the trick

A new question about this option,
how can I add the irqpoll option to elilo.conf so that I doesn't need to manual add the option at boot?

metaschima · 02-07-2014, 05:37 PM

Add it to the append option.
