Austin,

Toolchain #1:
kernel header linux-2.6.28.1, gcc-4.3.2, binutils-2.9, uclibc-0.9.30

Toolchain #1:
kernel header linux-2.6.27.10, gcc-4.2.4, binutils-2.9, uclibc-0.9.30


busybox which generates a kernel panic:
file /nfsroot/bin/busybox
/nfsroot/bin/busybox: setuid ELF 32-bit LSB executable, MIPS, MIPS32 
rel2 version 1 (SYSV), dynamically linked (uses shared libs), stripped
build with toolchain #1

file /var/lib/tftpboot/vmlinux
/var/lib/tftpboot/vmlinux: ELF 32-bit LSB executable, MIPS, MIPS32 
version 1 (SYSV), statically linked, not stripped
build with toolchain #1

Working busybox:
bin/busybox: setuid ELF 32-bit LSB executable, MIPS, MIPS32 version 1 
(SYSV), dynamically linked (uses shared libs), stripped
build with toolchain #2

I'm a bit confused, I've set mips32r2 in buildroot for toolchain #1 and 
for toolchain #2.

Thanks for your answer.
Regards
