Question eth0: interrupt(s) dropped! messages 

Forum: PCMCIA Network Adapter Issues
Date: 1999, Nov 01
From: Rick Lerner rlerner

PROBLEM:  My network PCCard appears to work fine, but /var/log/messages
contains hundreds of lines containing the following error message:

	 Nov  1 15:46:06 localhost kernel: eth0: interrupt(s) dropped! 

Any ideas what is wrong?

I recently updated my laptop from RedHat 5.1 to 6.1.  To complete the
upgrade I needed to add an ifcfg-eth0 file with the following contents:

/etc/sysconfig/network-scripts/ifcfg-eth0:
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=no

I also added links to /etc/rc.d/init.d/pcmcia in /etc/rc.d/rc[345].d

Otherwise, the pcmcia configuration files are the ones installed by RedHat.

Thanks for any information,

Message Administration

This form allows you to delete, move, or copy one or more messages. You can move messages by copying and deleting the original. The action will be applied to the messages you select above and all replies to those selected messages.


If you want to copy or move messages, specify the HyperNews path of a destination forum or message that all messages will be copied or moved to. The destination must already exist, so maybe create it first.

Path of Destination (a Forum or Message): (e.g. "test")

Notify Subscribers at destination
NO


If you want to delete messages (the default), specify that here. If you want to move messages, you need to delete the original messages; placeholders will be left pointing to where they were moved.

Delete Messages
NO


Caution: After deleteing messages (the default), if you have not copied them (i.e. no destination above), then the selected messages are not be recoverable.
