Hi all,

I have recently purchased a Dockstar, and I have some trouble making
it boot on ARMedSlack installed on a memory stick, despite reading
messages on this mailing list.

I have replaced the original uboot by the one described on
http://jeff.doozan.com/debian/uboot/ which is configured to boot from
After several attempts with Slackware, I have successfully booted
Debian on my memory stick using the procedure/script from
http://jeff.doozan.com/debian/, so the stick is OK :-)

I must mention that I don't have a serial cable; I have actived
uboot's netconsole, which is helpful... but not enough.

To install Slackware, I have installed the minirootfs from
and followed the instructions (mainly declare /dev/sda1 as '/' in

When trying to boot Slackware, here are the messages I can read:

Starting kernel ...

And nothing more. Then I have tried nmap, but no service answers, so I
don't know if the kernel as booted OK or not.

I have tried to add netconsole=@ to bootargs, but it looks
like the supplied kernel does not support netconsole.

Any hint?
