Hi!
I haven't reported kernel bug until now. I'll try to send as much
information as I can. I hope it is sufficient.
1. I see repeating (flood) messages "Oct 27 13:14:59 mclive5 kernel:
eth0: link up, 100Mbps, full-duplex, lpa 0x45E1" in my syslog - once per
second.
2. Frequency is probably one message per second because I see this on
every 61 seconds: "last message repeated 61 times". I'm not sure if the
problem is in the driver or in OS because I use Centos 5.5 with newer
kernel, but I don't have the same problem with other network adapters.
R6040 is build into kernet, not as a module.
3. keywords: modules, networking, kernel, problem, linkup, syslog,
r6040, MicroClient JrMX
4. kernel version - # cat /proc/version
Linux version 2.6.35.7-ns.i586 (root@localhost.localdomain) (gcc version
4.1.2 20080704 (Red Hat 4.1.2-48)) #15 Thu Oct 21 18:26:55 CEST 2010
SMP is disabled
5.
6. The problem is always presend. doesn't have to trigger it. only bring
interface up:
ifconfig eth0 up
7.1 Operating system is Centos 5.5 without updates. it's run as livecd
(my own modification). initrd is completely rewritten - it uses bash for
init script. init script just mounts the filesystem and ends with:
exec chroot . /bin/bash <<- EOF >/dev/console
echo "running init"
exec /sbin/init $level
EOF
root filesystem is AUFS that consists of:
one squashfs image
one tmpfs ram disk with size=200M
7.2. processor info:
Processor is Xcore86 MX at 1 GHz and it is i586 compatible
/proc/cpu reports Vortex86 SoC
flags : fpu tsc cx8

7.7 Other information that might be relevant to the problem
can't think of
8. Other notes, patches, fixes, workarounds
AUFS patch was added to kernel 2.6.35.7
no other patches to kernel
hardware is: http://www.norhtec.com/products/mcjrmx/index.html, but it's
not documented very well.
RAM: 512
I had similar problems with kernel 2.6.29 (not absolutely sure about
the version) and another hardware (i486 compatible - XCore86 DX CPU on a
Microclient JrDX), but the messages were output to the console and were
a lot faster - few messages per second.
Good Luck!
