Hi,
        I recently booted a NetBSD-4.0 MP kernel on my Dell 420, after having

run 3.0_STABLE for several years without problems. Mostly it works, except forthe following ethernet errors:


Aug  1 01:40:17 dirt /netbsd: ex0: transmit underrun (9000) @20
Aug  1 01:40:18 dirt /netbsd: ex0: transmit underrun (9000) @20, new threshold 
is 40

Aug  1 08:53:09 dirt /netbsd: ex0: transmit underrun (9000) @80
Aug  1 08:58:40 dirt /netbsd: ex0: transmit underrun (9000) @80
Aug  1 09:22:31 dirt /netbsd: ex0: transmit underrun (9000) @80

and associated interface Oerrs. On the switch side, a HP 2424m, I have alsoseen "Excessive CRC/alignment errors" on this port. These errors are new since

booting 4.0

The interface is configured as follows at boot time:

ex0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        capabilities=3f00
        enabled=0
        address: 00:b0:d0:ab:aa:c6
        media: Ethernet autoselect (100baseTX full-duplex)
        status: active
        inet 192.168.37.61 netmask 0xffffff00 broadcast 192.168.37.255
        inet6 fe80::2b0:d0ff:feab:aac6%ex0 prefixlen 64 scopeid 0x1
        inet6 2002:d040:f444:37:2b0:d0ff:feab:aac6 prefixlen 64

Nothing had changed in the configuration of the card, except for booting the
4.0 kernel (I'm still at 3.0_STABLE user land).

What would be the best way to troubleshoot this, or are there any configurationchanges I should consider?


        Thanks for any help.

        - Scott
