Hi,
Newbie alert! This is my first post and first steps with the Kirkwood
ARM stuff so please go easy on me.
I've just obtained a Dreamplug device, basically a slightly upgraded
Guruplug. Following the Armedslack install instructions I get a
solidly reproducible hang on initial kernel boot. For grins I saw
someone on the list had posted a 2.6.38.7 kernel and I installed the
uImage for that onto a memory card and booted... with exactly the same
result. My uneducated guess is that there is some module that is
locking the system up (wrong/missing) and/or I've forgotten something
really important!
I'm happy to provide additional data and try suggestions out, in fact
it would be a great learning experience on how the initial kernel
stuff works. I've pasted a failing boot below, and following that is
a working one using the kernel supplied with the device. Here's the
failing boot from the U-Boot prompt. The uImage file is on a FAT16
partition, /dev/sdb1, and the uinitrd is the same place and also
copied to the second ext2 partition, /dev/sdb2 (or in RAM if doing TFTP):

The system locks up absolutely solid at this point, every time,
whether I boot with the 2.6.38.7 kernel as above or if I boot, via
TFTP, the install kernel from Slackware 13.37. For comparison, here's
the boot from the stock kernel that comes with the Dreamplug:
