Hello,
I'm trying to get a ramdisk working on my EP88xc with uboot and linux
kernel v2.6.30. The ramdisk image is from
ELDK_4.2/ppc_8xx/images/uRamdisk.
At first I thought my issue was similar to
http://ozlabs.org/pipermail/linuxppc-embedded/2008-August/031204.html
but I'm not so sure anymore. I think my problem is with incorrectly
configuring my kernel.
Here is my console output:

So the kernel does say "Found initrd at 0xc3daa000:0xc3f6cb13", but then
"Unpacking initramfs... failed!
no cpio magic
Freeing initrd memory: 1802k freed"
What's going on here? Please help.

Hi Mikhail,
Try setting CONFIG_EXT2_FS=y, then recompile your kernel and reboot.

Hi Frank, just tried that but still getting the same "Unpacking

Hmm... according to "Kernel command line: console=ttyCPM0,9600n8
loglevel=7" you haven't
specified where root is. Add root=/dev/ram to the kernel command line,
and specify where the
init process is located (for instance init=/sbin/init).
I haven't tried Denks ramdisk image. You can create one for yourself
using dd, gzip and U-Boots
mkimage tool. If the ramdisk image is larger than 4MB, you must either
change the default
CONFIG_BLK_DEV_RAM_SIZE=4096, or set ramdisk size in the kernel command line.
Btw, I use an older kernel than you use, but I have these defined:
CONFIG_BLK_DEV=y
CONFIG_BLK_DEV_LOOP=y
CONFIG_BLK_DEV_RAM=y
CONFIG_BLK_DEV_RAM_COUNT=16
CONFIG_BLK_DEV_RAM_SIZE=4096
Maybe they're obsolete now, but you can try to add them to your defconfig file.
Good luck ;-)

Thanks Frank, this seems to be leading me down the right path. I tried
some of those defines out yesterday and they got the kernel to at
least attempt to load the ramdisk, so I'm getting somewhere. Also
added root=3D/dev/ram (also tried /dev/ram0) and init=3D/sbin/init but for
now things are failing before processing those args.
I haven't tried CONFIG_BLK_DEV or CONFIG_BLK_DEV_LOOP and am still
playing around with the values for CONFIG_BLK_DEV_RAM_COUNT and
CONFIG_BLK_DEV_RAM_SIZE. Strangely, the DEV_RAM defines are completely
missing from my config so I have to put them in manually... (as
opposed to via menuconfig). I'll post back when it's working or when
I've tried all of this and still am getting some error.
Meanwhile a side question - why does BLK_DEV_RAM_COUNT default to 16?

If you don't have CONFIG_BLK_DEV defined, you can't have CONFIG_BLK_DEV_RAM_COUNT
or CONFIG_BLK_DEV_RAM_SIZE. Use 'menuconfig' to help straighten this out.
> Meanwhile a side question - why does BLK_DEV_RAM_COUNT default to 16?
This is just the number of unique RAM disk devices supported.

I see, thanks Gary, I'll leave that unmodified then. I only really
need 1 but it doesn't seem to negatively affect anything if I leave it
at 16.
Just as an intermediate update on the issue, I've made progress and it
hangs later down the line, see below:

Wow... I just found out that it's not actually "hanging" at this
point.. it's just working in "slow motion"... I found out by leaving
the machine and coming back half an hour later to find additional
output and eventually even a prompt.
Here is what's happening:
*************************************************************************
RAMDISK: gzip image found at block 0
VFS: Mounted root (ext2 filesystem) on device 1:0.
Freeing unused kernel memory: 112k init
<4 minutes pass>

<2 minutes pass>
starting pid 403, tty '': '/etc/rc.sh'
< etc... >
*************************************************************************
I've tried a couple different ramdisk images (another one with a much
older version of busybox), with similar results. Anybody have an idea
about what's going on here?

Hi Mikhail,
This is very interesting. I recently experienced a similar problem when
upgrading from 2.6.26-rc6 to 2.6.31-rc1 (torvalds mainline kernel).
I didn't had the time to figure out what was happening, so I went back to
2.6.26-rc6. Just for the test, could you try to go back to 2.6.26 and see i=
f
the problem remains?

Frank! That worked like a charm! I downloaded linux-2.6.26 source from
git.kernel.org, inserted the config options previously mentioned,
compiled ok, keeping U-Boot ramdisk and my DTS same it booted right up
and no more "slow motion" issue.
Thanks! Now I just need to make myself a custom ramdisk.

If you have time, could you bisect to see when the slowdown was introduced?

I'm leaving in 5 minutes, but I'll try to find some time next week to
check this out.

Scott, I tested with kernels 2.6.28, 2.6.29 and 2.6.30 all obtained
from git.kernel.org and configured the same.
So, on my EP88xc board 2.6.28 and 2.6.29 work ok, 2.6.30 has the
slowdown issue after loading a ramdisk.
After doing this testing I have a side question:
If I modify just arch/powerpc/configs/ep88x_defconfig, not all changes
are reflected in the resulting .config when i do "make
ep88x_defconfig; make uImage". I ended up having to modify
arch/powerpc/Kconfig, arch/powerpc/configs/ep88xc_defconfig,
fs/ext2/Kconfig and init/Kconfig to get "make ep88x_defconfig; make
uImage" to create a properly configured image, but this really doesn't
feel right. What's the proper way to set up a defconfig?
Thanks,
Mikhail Zaturenskiy

What changes are you trying to make to the config, and what did you
change in the Kconfig files?

You should definitely not do that. In fact, I'm surprised kconfig
didn't complain about the duplicate symbols.
Perhaps CONFIG_BLK_DEV is unset?

Hmm, missed this. I'm not sure why the subsequent changes didn't take
effect -- what did the .config look like after sucking in the defconfig
changes, but without any Kconfig changes?
In any case, the best way to make changes is with one of the config
editors (menuconfig, etc).

CONFIG_BLK_DEV is enabled in that output. That was the only change that
I saw you make to the config in the previous e-mail -- no
CONFIG_BLK_DEV_RAM, etc:

OK, looked at the attached defconfig (didn't notice that until after I
hit send).
Try omitting the spaces around the equal sign. BLK_DEV likely worked
because it's default y and because you removed the "is not set" line,
not because you added the = y line.
