Hi,
*read below for a problem report against the tulip network driver[1]
It looks like the bridging feature of the kernel has changed between 2.4.17 and 18.
I have a machine running 2.4.16 running as a bride without problem. While testing the network cards for another bridge I had to restart. Unfortunately, it didn't complete. Nothing would respond except for sysrq. I was able to sync, unmount, and reboot successfully.
Debian does this for you automatically, but if you do it manually it does the same thing.
o Setup a bridge like normal o start it up o ifconfig br0 down o brctl delbr br0 *boom*
2.4.16,17 work just fine, but 2.4.18 does not. Looking through the changelog, 2.4.18-pre4, or 5 look suspect. Also, it is not fixed in 2.4.19-pre6. I can test the 2.4.18-pre kernels if you'd like, just let me know.
[1] Also several times I was able to get my tulip network card to stop forwarding packets after a soft-reboot from the lockup mentioned above. I was able to reproduce this in 2.4.17, 2.4.18, 2.4.19-pre3-ac4 (possibly 2.4.19-pre5-ac3 though didn't check to make sure but I used it several times during my testing), and 2.4.19-pre6. None of the other network cards in this machine did this (3c509-isa, pcnet32-pci, eepro100-pci)
I don't have a serial cable ATM but I could buy one in a few days if a ksymoopsed sysrq-t would help.
