Slow boot & the message that comes with it

[sunfromhere]

Hello! Ubuntu is 12.04, PC is Eee PC (dual core Atom with HT, 1.4 GHZ, 2GB RAM).

I have this hole in my boot time, shown in dmesg:

[ 8.460923] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null)
[ 21.503622] ADDRCONF(NETDEV_UP): eth0: link is not ready

Total boot time is 28 seconds, which I don't mind, I just wonder what this part means: EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null), and why does it make a 10 seconds pause in the boot. I googled it, but didn't get any smarter.

Thanks!

i was able to make that shorter by using uefi boot in my bios, using 13.04 here
the second line you posted is the real issue, looks to be ~12 seconds of your boot time
try disabling ipv6 and see if it boot faster, use ipv6.disable=1 in your kernel boot line and see if it boots faster

Ipv6 is disabled:

cat /proc/sys/net/ipv6/conf/all/disable_ipv6
1

[pqwoerituytrueiwoq]

when i boot using that, the command does this

~$ cat /proc/sys/net/ipv6/conf/all/disable_ipv6
0

I changed it*, now it is also 0. Now I get two holes:

[ 7.999398] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null)
[ 20.872102] ADDRCONF(NETDEV_UP): eth0: link is not ready

[ 27.573025] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready
[ 37.784274] wlan0: no IPv6 routers present


*in /etc/sysctl.conf
