Question: PCMCIA Problem with 3COM 3C562D/3C563D "eth0: interrupt(s) dropped" 

Forum: PCMCIA Installation and Configuration Issues
Date: 2000, Mar 17
From: John Auld jxa

I have a working install of Linux (tomsrtbt) with networking enabled via PCMCIA services on a laptop. The networking works properly (e.g. I can ping hosts etc.) but the console is over-written with warning message "eth0: interrupt(s) dropped!", which makes the system very hard to use. I have searched for a solution through the PCMCIA and Ethernet HOWTO's and www.dejanews.com with no success. I can't tell if this is a problem with the card configuration or the Net Card driver or what to do to clear it. Your advice would be greatly appreciated. John Auld

Dropped interrupts Re: Question: PCMCIA Problem with 3COM 3C562D/3C563D "eth0: interrupt(s) dropped" (John Auld) Date: 2000, Mar 17 From: David Hinds <dhinds@pcmcia.sourceforge.org>

What sort of laptop? Can you capture the startup messages from the PCMCIA drivers? Interrupts are not being delivered to the card. It is not a problem with the driver for the card, it is a problem with the socket driver. It could be that this would be fixed by upgrading the PCMCIA package, but I don't know what version you've got. -- Dave

Thanks for the prompt reply. The Laptop is a Twinhead Voyager. dmesg reports a Cirrus PD6729 PCI-to-PCMCIA chip and the PCMCIA services load the following modules (listed from `cat /proc/modules`) 3c589_cs 1 0 serial_cs 2 1 ds 2 [serial_cs 3c589_cs] 2 i82365 5 2 pcmcia_core 9 [serial_cs 3c589_cs ds i82365] 8 Software versions kernel = 2.0.37 PCMCIA Services = 3.0.12 3c589 driver = v0.99H I have used a boot floppy version of Linux as a means to recover data on Win9x laptops at work that are un-bootable or too unstable for use (I will need to use this many times!!!) and I have not yet read all of the init and config scripts, but I can configure the PCMCIA start up options if I need to. Thanks again for your help. John Auld

Probably just an interrupt conflict Re: Hardware & Software details (John Auld) Date: 2000, Mar 20 From: David Hinds <dhinds@pcmcia.sourceforge.org>

You probably just have an interrupt conflict with some other system device. I'd start by excluding interrupts in /etc/pcmcia/config.opts and see if that fixes the problem. -- Dave
