Untested at this stage.

This kernel is for Dreamplugs only and addresses a few issues including the new U-Boot(s) that use a different machine id.

You can download at
      http://www.spinifex.net/plugs/downloads/dreamplug/kernel/dreamplug-3.3.tar.xz

Install instructions are at
     http://www.spinifex.net/plugs/downloads/dreamplug/kernel/README.kernel

The alternate features are described at
    http://www.plugcomputer.org/plugforum/index.php?topic=6063.msg19900#msg19900

Its probably just a case of blacklisting the libertas and mwifiex drivers.
Post the output    from

# lsmod

if you are not using bluetooth

blacklist

btmrvl and btmrvl_sdio

You might have to explicitly load uap8xxxx

with

# modprobe uap8xxx

Hi,
I have a problem with setting up bluetooth.
Code:
root@dreamplug-debian:~# /etc/init.d/bluetooth start
Quote
Starting bluetooth:Illegal instruction

Before that it exited with segmentation fault. I solved it by installing libcap-ng0_0.6.6-1_armel.deb from Ubuntu's repo as suggested here.

Before that I saw error messages in dmesg:
Quote
Bluetooth: request_firmware(helper) failed, error code = -2
Bluetooth: Failed to download helper!
Bluetooth: sbi_interrupt(dfa37400) card or priv is NULL, card=de81f340
Bluetooth: Downloading firmware failed!

The solution according to this is to create these symbolic links:
Code:
root@dreamplug-debian:~# ln -s /lib/firmware/mrvl/sd8688_helper.bin /lib/firmware/sd8688_helper.bin
root@dreamplug-debian:~# ln -s /lib/firmware/mrvl/sd8688.bin /lib/firmware/sd8688.bin

But I stucked here. Any idea?
