Hi,
I got a problem with the 2.6.16 kernel running on my
OSK. It panics after (or when) running init. I'm not
sure what the problem is and MontaVista's kernel works
fine with my rootfs.
The same kernel and rootfs, however, works with our
other OSK5912 board....
Here's the log and backtrace of the problem.
Appreciate your help on this.

We experienced similar problems on our OSK5912. The problems are SDRAM setup
related and can be solved by updating to the latest U-Boot version. Please
download and install the top-of-git version and give it a try.
Best regards,
Stefan

Anybody have a patch to check this in the board-osk.c? This bug seems to
occur repeatedly so it would be nice to patch it away in the kernel
also.
Regards,
Tony

I don't think this would work. SDRAM setup has to be done correctly in the
bootloader (U-Boot or whatever is used) and can't be corrected later on by
linux itself.

Stefan

Hi Tony, Stefan,
I am already using the 1.1.4 version of u-boot and
the problem is still there. Is there a newer version
of the bootloader?
Thing is everything was working fine, until I
forced a kernel panic to get a backtrace (my bad).
Then this problem started. Any idea where the problem
might be from?
Thanks!

Yes, I am not talking about the release version 1.1.4 but of the current
top-of-git tree version. Please download and test the latest version from:
http://www.denx.de/en/Software/GIT
Please let me know, if your problem still occurs using this version.
Best regards,
Stefan
