Kernal upgrade on 7.1 leaves Ethernet Card (NIC) inoperable
Last modified: 2007-04-18 12:43:10 EDT
Description of Problem: We have a Linux 7.1 system on an IBM 300GL PC with an SMC 8432 NIC (Tulip chip # 21041) which works fine
'straight out of the box'. When we upgraded the Kernel to -34, the NIC seems to work fine but no packets traverse the network. No unusual or
error messages appear in the logs.
If we run linux.bak, all is ok.
I noted that there is a newer Tulip chip driver in the the kernel update.
Version-Release number of selected component (if applicable): SMC 8432 BT (Tulip chip 21041)
How Reproducible: after upgrading to the latest kernel for 7.1, we can boot linux and the network interface fails. We can boot linux.bak and the
network interface works.
Steps to Reproduce:
1. Build Linux 7.1 on an IBM 300GL with an SMC 8432B NIC
Can ping NIC IP address but no other IP address on the LAN. No other protocols tested.
Normal LAN connectivity
what is the previous kernel version you used?
note that 2.4.9-34 also has the "tulip_old" driver, which is the older driver of
the tulip driver, eg the one you probably were using.
To switch to this driver you need to edit /etc/modules.conf and replace tulip
with tulip_old there
