Eth0 is being up and down for several time during boot

Question

My wicd doesn't connect to eth0 on the first attempt after boot up. It is configured to eth0 always have a higher priority to connect.
My dmesg shows that eth0 being up and down for several time during boot. I have e1000e in my MODULES list.
Here is my rc.conf
# /etc/rc.conf - Main Configuration for Arch Linux
# LOCALIZATION
# LOCALE: available languages can be listed with the 'locale -a' command
# DAEMON_LOCALE: If set to 'yes', use $LOCALE as the locale during daemon
# startup and during the boot process. If set to 'no', the C locale is used.
# HARDWARECLOCK: set to "", "UTC" or "localtime", any other value will result
# in the hardware clock being left untouched (useful for virtualization)
# Note: Using "localtime" is discouraged, using "" makes hwclock fall back
# to the value in /var/lib/hwclock/adjfile
# TIMEZONE: timezones are found in /usr/share/zoneinfo
# Note: if unset, the value in /etc/localtime is used unchanged
# KEYMAP: keymaps are found in /usr/share/kbd/keymaps
# CONSOLEFONT: found in /usr/share/kbd/consolefonts (only needed for non-US)
# CONSOLEMAP: found in /usr/share/kbd/consoletrans
# USECOLOR: use ANSI color sequences in startup messages

# HOSTNAME: Hostname of machine. Should also be put in /etc/hosts

# Use 'ip addr' or 'ls /sys/class/net/' to see all available interfaces.
# Wired network setup
# - interface: name of device (required)
# - address: IP address (leave blank for DHCP)
# - netmask: subnet mask (ignored for DHCP) (optional, defaults to 255.255.255.0)
# - broadcast: broadcast address (ignored for DHCP) (optional)

# Setting this to "yes" will skip network shutdown.
# This is required if your root device is on NFS.

# Enable these netcfg profiles at boot-up. These are useful if you happen to

Any hint for tracing the root of this problem? Thank you very much!

Hi ...
If you have moved the Safari application from the Applications folder, move it back.
As far as the cache goes, there's a work around for that when you can't empty the Safari cache from the menu bar.
Go to    ~/Library/Caches/com.aple.Safari.Cache.db.  Move the Cache.db file to the Trash.
Try Safari.
Mac OS X (10.7.2)   <  from your profile
If that is corrrect, you need to update your system software. Click your Apple menu icon top left in your screen. From the drop down menu click Software
Update ...
~ (Tilde) character represents the Home folder.
For Lion v10.7x:  To find the Home folder in OS X Lion, open the Finder, hold the Option key, and choose Go > Library
