Cut boot time

I have Fedora 16 LXDE spin on my Acer Aspire One 722 netbook. I've replaced the stock HDD with a 120 GB SSD, and increased the RAM from 2 GB to 4GB.
I'm disappointed with the boot times. It will frequently take over a minute to boot up, which with an SSD is unacceptable. I blacklisted the acer_wmi module, which cut it somewhat, but there's still a lot of wasted time. Here are the last three dmesg entries:

Code:
[   15.536629] wlan0: moving STA 00:12:17:7a:73:d1 to state 3
[   25.586138] wlan0: no IPv6 routers present
[   31.609179] hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj.
Can I somehow keep wlan0 from starting at bootup? What about the IRQ timing, etc.?

You need to run
systemd-analyze blame
and post the result.

Re: Cut boot time

One option is install F17
Code:
$ systemd-analyze blame | grep console-kit
$
Seriously though, install systemd-gtk, then start systemadm. It's a decent GUI for controlling systemd services and units.

Re: Cut boot time

From that list I would immediately get rid of livesys-late.service. If you've installed the system from a livecd, this seems to remain on the install.

$ sudo systemctl disable $SERVICE

for example:

$ sudo systemctl disable livesys-late.service
