Most recent kernel where this bug did not occur:2.6.14.3
Distribution:Fedora Core 4
Hardware Environment:P5P800 Asus Mobo uses sk98lin driver
Software Environment:boot in runlevel 3
Problem Description:errors in dmesg and kernel logs as soon as the network card
is detected and apparently each time a packet is received. Files downloaded seem
fine, no corruption.
RX packets:68853 errors:0 dropped:0 overruns:0 frame:0
TX packets:65015 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000

Steps to reproduce:boot machine as soon as the eth0 is up messages appear

 kernel: SELinux: initialized (dev binfmt_misc, type binfmt_misc), uses
genfs_contexts
 kernel: eth0: network connection up using port A
 kernel:     speed:           100

 kernel:     duplex mode:     full
 kernel:     flowctrl:        symmetric
 kernel:     irq moderation:  disabled
 kernel:     scatter-gather:  enabled
 kernel: <NULL>: hw csum failure.
