I tried the normal tricks (gdb > -c /proc/kcore vmlinux, objdump -d etc.) but none of the places list this > address. ffff81002fe80000 is the address of the slab object. 00000000000008a8 is supposed to be the caller's text address. It appears that __builtin_return_address(0) is returning junk. Perhaps due to -fomit-frame-pointer. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
