Hi,
I'm running a recently-compiled 2.2.16 final kernel, using distribution RedHat
6.2, and I'm seeing seemingly random problems with my ethernet connection,
using a 3Com 3C905B Cyclone (3Com's Fast EtherLink XL 10/100/BNC/AUI network
card). It doesn't seem to be a network problem - I have one other machine
running 2.2.15 with the same type of card, and there are no problems. Has
anyone else seen this? Is there a fix?
Randomly, web pages will fail to load, connections will time out, and so forth.
The most noticeable symptoms are printed below:
[root@DILITHIUM ramorris]# nslookup www.kernelnotes.org
*** Can't find server name for address 18.70.0.160: No response from server
*** Can't find server name for address 18.71.0.151: No response from server
*** Can't find server name for address 18.72.0.3: No response from server
*** Default servers are not available
And sometimes, randomly:
[root@DILITHIUM ramorris]# nslookup www.kernelnotes.org
*** Can't find server name for address 18.70.0.160: No response from server
*** Can't find server name for address 18.71.0.151: Timed out
*** Can't find server name for address 18.72.0.3: Timed out
*** Default servers are not available
Also, I sometimes get ping results like the following:
[root@DILITHIUM ramorris]# ping search.yahoo.com
PING search.yahoo.com (204.71.200.99) from 18.244.1.45 : 56(84) bytes of data.

--- search.yahoo.com ping statistics ---
4 packets transmitted, 4 packets received, +4 duplicates, 0% packet loss
round-trip min/avg/max = 0.3/37.8/76.7 ms
Notice the incorrect 169.254.122.98 address in the ping result - ping seems to
print this exact IP address no matter what host I try to ping.
One or more of these problems will occur several times if the commands are
repeated, then within 30 seconds to one minute they will disappear. The
problem did not occur with 2.2.15 or anything before, and seems to get worse
the longer the system is up (I don't notice the problem within a few hours after
rebooting).
I have also noticed that my dmesg log is full of line after line of:
eth0: Transmit error, Tx status register 82.
And ifconfig reports lots of network errors:
eth0 Link encap:Ethernet HWaddr 00:50:DA:6A:BE:C4

dmesg reports the following information on my ethernet card:

Enabling bus-master transmits and whole-frame receives.
And finally, the kernel info;
[root@DILITHIUM ramorris]# uname -a
