Switching back to the core-image-default non-static bash version, didn't work. I get no bash prompt, even through I specified init=/bin/sh for the kernel bootargs

What should I do now to debug this issue further?

I have disabled image-prelink by not including it in my local.conf as follows:

# Remove image-prelink for PowerPC 32-bit and 64-bit targets.
USER_CLASSES ?= "buildstats image-mklibs"

Any thoughts on what I can try to do next, to narrow down the issue, with bash working statically, but not when linked with shared libraries?

Best regards,
