PANDABOARD ES BOOT TIME

[Parin Choganwala]

Hi Guys,

I am trying to reduce boot time of Pandabaord with Ubuntu 11.10. Follwing is partial output of dmesg.

28.172912] (stk) :line disc installation timed out
[   28.172943] (stk) :ldisc_install = 0
[   28.275360] (stk) :ldisc_install = 1
[   28.570770] fuse init (API version 7.16)
[   29.273956] (stk) :line disc installation timed out
[   29.273956] (stk) :ldisc_install = 0

[   30.375518] (stk) :line disc installation timed out

[   59.488677] omap-abe-dai omap-abe-dai: omap_abe_dai_startup: MultiMedia1

it says disc installation timed out. How can I fix this ? any idea?

Thanks

If you aren't interested in Bluetooth, You can disable the TI-ST line discipline drivers (under device drivers->Misc devices).

In case you do want them, You need to start the service UIM upon boot - to get rid of this error.

well, if you really care about boot time, you will need to customize
the ubuntu kernel config quite a bit. ubuntu is supposed to be a
general purpose OS, and as such there are tons of drivers/configs
enabled that you can remove to optimize the boot time. also if you
have a 'static' boot configuration you will probably want to get rid
of initramfs as well, and customize the services started at boot time.

If you start with a simple root FS based on ubuntu-core (see
http://omappedia.org/wiki/OMAP_Ubuntu_Core) without initramfs and with
a custom kernel, you will see that boot time is largely improved
already compared to the regular -desktop image.

Thank you Pavan and Nicolas for your inputs.

@Nicolas

Can you please provide me starting points for kernel config and how to customize ubuntu?

Thank You
