Description Simon Falvey 2001-05-07 14:47:53 EDT

Description of problem:
After installing RH7.1 I can no longer use the network. the pcnet32 module
loads on boot but interface fails to come up. The following is in dmesg

pcnet32_probe_pci: found device 0x001022.0x002000
     ioaddr=0x006600 resource_flags=0x000101
PCI: Found IRQ for device 00:11.0
eth: PCnet/FAST 79C970 at 0x6600 warning: PROM address does not match CSR

     SRAMSIZE=0x7f00, SRAM_BND=0x4000
pcnet32: pcnet32_private lp=c34a0000 lp_dma_addr=0x34a0000 assigned IRQ 11
pcnet32.c: v1.25kf 26.9.99 tsbogend@alpha.franken.de

Doing a quick search on the web finds a number of other people with a
similar problem. The URL to one such post is above although this guy is
using Debian.

Further to this if I unload the pcnet32 module and cat /proc/interupts the
system then hangs and must be powered off.

System was installed over network without issue. 2 or 3 boots later it all
goes wrong.

How reproducible:

Steps to Reproduce:
1. Install RH7.1 on a system with AMD 79c970 ethernet card
2. Reboot

Actual Results:  As in description. Plus ifconfig states MAC address is 00
00 00 00 00 00

Expected Results:  The ethernet card should work without issue.

Additional info:

There is at least one posting

lists the offending lines of code but says they are only in 2.4.3, RH7.1 of
course installs 2.4.2-2 Has any additional code been stitched into this

FYI this system is a firewall and has no local floppy or CD only way of
performing data exchange is via ethernet. No compilors or source installed
Comment 1 Simon Falvey 2001-05-07 14:51:31 EDT
Booting off bootnet image does not re-initialise the card. If there is any way
you can think of to get the card working in-situ please let me know otherwise I
will have to remove the hard drive and perform a rebuild externally.

"FYI this system is a firewall and has no local floppy or CD only way of
 performing data exchange is via ethernet. No compilors or source installed
 either." makes it a bit hard.....

Other than that, we are working on an erratum kernel which has an updated
pcnet32 driver; A snapshot of the work can be found in rawhide.
Comment 3 Brian Brock 2001-05-08 10:11:23 EDT
the newer 2.4 kernel appears to have the fix that you pointed to, whihc does the
16-bit check first to avoid breaking older cards.
Comment 4 Alan Cox 2001-05-19 15:18:32 EDT
This one is resolved in current -ac kernels. Or should be. There was a period
the driver failed on a few obscure card variants.
Comment 5 Simon Falvey 2001-05-21 02:52:39 EDT
Agreed. I compiled 2.4.4 from source and transfered it via my Agenda Linux PDA 
to the firewall box and can now use the NIC. Any idea when a new kernel rpm 
will be released?

Using ifconfig, assign the MAC address to the card.  Find out what the card's 
MAC address is and do the following:

ifconfig eth0 hw ether ############

Where "############" is the MAC address.
