$ qemu-system-sparc -m 32 -nographic \

    -boot d


It fails in inflate() called from sys/lib/libsa/loadfile_elf32.c:419

DTrace: Add support for CTF sections in the netbsd elf image, load these
at boot.
Add a ksyms_mod_foreach() function to iterate a callback function over the
set of elf symbols for a specific module (netbsd included).
Add kern_ctf.c and mod_ctf_get() to allow the retrieval and decompression
of CTF sections for a specific module.

The failed read is to maxp=0xf030d71c size=252

If i disable boot_load_ctf, then the kernel loads and boot fine.

I guess qemu does something differently than real hw, since my
javastation can boot current ok.

I'm not sure I follow maxp dances that happen in loadfile_elf32(), but
I don't have time to look deeper now.
