Hi Scott,
I am currently trying to bring up 2.6.39 kernel on a target based on MPC8247
Processor, using the attched .dts file . I get the below logs while the kernel
is booting.
I see that the unflattening of the device tree and the initial loading of the
kernel and ramdisk file system is happening correctly. Can you point me where
exactly I can look for
this issue. I am attaching the .config and .dts file I am using.
There doesn't seem to be anything wrong with the kernel in this log.
The failure is in the user code - in particular, udev is giving up
with these errors:
/sbin/udevstart: '/lib/libc.so.6' library contains unsupported TLS
After that, all is lost as there will be no console, etc, for the
rest of the system to use...
You need to examine how you built the root file system and why you
are getting these errors. This problem seems to be unique to uclibc
