PCMCIA Network Dropping Interrupts
Last modified: 2008-05-01 11:37:55 EDT
Using RH6.2 Workstation install (with applicable updates), started getting
kernel error messages after switching from KDE to GNOME.
kernel: eth0: interrupt(s) dropped!
This causes all network activity to stop and the pcmcia service must be
I installed KDE as my desktop environment WITHOUT any Gnome components.
Upon installing Gnome and Helix, started getting the above errors at random
intervals ranging from 1 sec to hours after restarting the pcmcia service.
The module man page states:
eth#: interrupt(s) dropped!
Indicates that the driver did not receive an interrupt notification for
some reason. The driver will poll the card (with a significant performance
penalty) if the problem persists. The most likely cause is an interrupt
conflict and/or host bridge configuration problem.
I suspect this is related to ESD as it was not installed prior to Gnome and
did not have this message until this time. Can this be confirmed? Any
work-arounds? I tried turning off sound events and even the sound server
in Gnome-config without change.
Have tried changing the module "max_interrupt_work" and "irq_list" options
in /etc/pcmcia/config.opts to no avail.
Configuration as follows:
Toshiba Tecra 550CDT Laptop
4 G HDD
160 M Mem
Have ran RH on this laptop since 5.1 :-)
Do you see this problem with the RH gnome rpms installed, or just Helix ?
