I had posted about this earlier but have sine found new facts. I am running a Triton Chipset based P133 with AHA2940 scsi card, Linksys LNEPCI ethernet card, STB 2meg pci video card, Soundblaster 16, 32 megs of ram. With the 2.0.0 kernel any network activity that hits the ethernet card causes a hard lock with no output to syslog. This happens with the Linksys and also with an NE2000 isa clone. This system is rock solid under the 1.2.13 kernel and I am running it that way now. All of the 2.0.0 upgrades to Netkit, ppp, procps, etc have been applied and are stable with the 1.2.13 kernel.
I began to try to back trace through the kernel revisions by building 1.99.7 and installing that. The system seemed to come up fine but I was unable to ping anything on the local lan. The system did not crash when packets hit the card but nothing got out or in. Other machines on the net could not get any responses to pings. When I terminated the outbound ping on the machine with the problem I got an error message indicated that a socket had been destroyed:
Socket destroyed (r=0 w=2992)
I then tried a netstat -r to check the routing and the system locked hard agin apparently while trying to resolve an ip address to a name. The behavior under 2.0.0 is similar, excpet that the system locks at the ping, and never come back.
I've included boot time messages from the last 1.99.7 boot below for anyone who is interested in helping. Note that the message at the end about eth0 have no media is incorrect, I get it under all three of the kernels I am working with, and occaisionally under 1.2.13 I will see a message like this:
Jul 4 12:27:14 ronin kernel: eth0: Media is AUI.
This is truly bogus since the card supports 10baseT and 2baseT, not even an AUI on it. Nevertheless everything runs fine under 1.2.13. I would REALLY like to move up to 2.0.x but am not sure what to do next in trying to get this resolved. I'd appreciate any advice.
Thanks in advance, Chuck
