Question: Socket EA System Hang 

Forum: PCMCIA Network Adapter Issues

Hi all, I've been trying unsuccessfully to get my eth0 card working with my new laptop. System: Dell Latitude CPi R400GT PC Card: Socket EA Ethernet Kernel: 2.2.14 PCMCIA: 3.1.8 Changes: Added exit 0; in pcmcia/network to prevent hangs (see below) Messages: ------------------------ initializing socket 1 eth0: NE2000 Compatible: io 0x300 irq 3 auto xcvr hw_addr 00:C0:1B:00:5E:27 socket 1: Socket EA Ethernet executing insmod /lib/modules/2.2.14/net/8390.o executing insmod /lib/modules/2.2.14/pcmcia/pcnet_cs.o executing ./network start eth0 ---------------------------- At which point, the system hangs until the card is ejected. When it is, the following messages are given: ---------------------------- Hw. address read/write mismap 0 Hw. address read/write mismap 1 Hw. address read/write mismap 2 Hw. address read/write mismap 3 Hw. address read/write mismap 4 Hw. address read/write mismap 5 eth0: interupt from stopped card ---------------------------- The card worked fine in my old laptop (Compaq Aero C33, running linux 2.0.0), and the my modem card (psion dacom gold card) works fine in the Dell as well as the Compaq. In the documentation, it says that it's necessary to use ifport to manually set the interface for EA cards - doing this or not seems to make no difference, the system still hangs with the same errors. Occaisonally it won't hang when the interface is brought up, but will on receiving any traffic. In this scenario the messages are: -------------------------------------- eth0: mismatched read page pointers 0 vs e. eth0: mismatched read page pointers 0 vs ff. eth0: mismatched read page pointers 0 vs ff. eth0: mismatched read page pointers 0 vs ff. ... eth0: unexpected TX-done interrupt, lasttx=0. eth0: too much work at interrupt, status 0xff eth0: interrupt from stopped card --------------------------------------- Other miscellaneous messages from when the card is inserted but nothing has been done to it: 'probe' gives: PCI bridge probe: TI 1255 found, 2 sockets. 'cardctl ident' gives: product info: Socket Communications Inc, Socket EA PCMCIA LAN Adapter Revision E, Ethernet ID 00c01b005e27 manfid: 0x0104, 0x000 function: 6 (network) 'cardctl status' gives: 5V 16-bit PC Card funciton 0: [ready] ------ This looks like a driver problem, does anyone have any information or ideas about it? Thanks, Rob Sanderson

Resource conflict? Re: Question: Socket EA System Hang (Robert Sanderson) Date: 2000, Jan 21 From: David Hinds <dhinds@pcmcia.sourceforge.org>

My first guess would be that this is either an IO port or interrupt conflict. Since you've already built 3.1.8, I'd try re-building it with "PnP BIOS support" switched on, and see if that makes a difference: this should make PCMCIA do a better job of avoiding resource conflicts. Or, you can try excluding port 0x300-0x31f and irq 3 in /etc/pcmcia/config.opts. -- Dave

Unfortunately the same results happen with the port excluded as well. :( In the docs it says to set ifport. The card reports as 'auto' in the syslog, but trying to set it to 10baseT results in the same hang as touching the card any other way. Is this significant perhaps? Or any other suggestions? Many thanks, Rob Sanderson
