Yes, I have had it enabled the whole time. As noted in another email, it appears that U-Boot puts the FDT in such a place that Linux overwrites it with the BSS. The CONFIG_PROVE_LOCKING=y option expands the BSS by a large amount, which causes the error. It isn't directly lockdep related. I don't know if this is a U-Boot problem or a Linux problem. I have no idea how to fix the bug. Thanks, Ira _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
