Hello,
- PROBLEM :
Firefox browser is responding very slowly. Lots of write access to my hard disk.
- INFORMATIONS :
This message appears hundreds of times in /var/log/messages or in the output of the command 'dmesg' :
"...eth1: Too much work at interrupt, status=0x0000ffff..."
As we can see it concerns here eth1 and it's my Via Rhine network card :
(you need to install ethtool package to have the 'ethtool' command)
- SOLUTION :
After searching the web I didn't find anything suitable for me so I checked the via-rhine.c driver source code (you gotta love linux just for this to be possible) and seen this :
For those who don't understand this : RTFM
I listed the via_rhine kernel module like this :
I then check the available options of this kernel module :
The line "parm:           debug:VIA Rhine debug level (0-7) (int)" means we can pass the option "debug" to the via_rhine kernel module, specifying an integer between 0 and 7.
To make this option permanent we can append this to the file /etc/modprobe.d/options :
Then reboot your machine and it solved the problem (at least for me).
- CONFIG :
*kernel : 2.6.27-9-generic
*distro : Kubuntu 8.10
*cpu : Intel(R) Pentium(R) 4 CPU 3.40GHz
P.S : I tried to be as "newbie friendly" as I could
P.P.S : My first week on Kubuntu in 12 years of linux experience and to me : debian is the best linux distro, kde is the most user friendly user interface, and I plan to code in C++ with Qt4 so Kubuntu is suitable for that (though to me KDE should have less visible bugs and a better theme manager)
P.P.P.S : My last experience was the gentoo+gnome world
