While building 2.6.12-rc1-bk1 with attached config I get "Inconsistent kallsyms data".
Setting CONFIG_KALLSYMS_EXTRA_PASS or CONFIG_KALLSYMS_ALL fixes the problem. Noted differences: --- System.map +++ .tmp_System.map -c03cf83c D kallsyms_markers -c03cf8d4 D kallsyms_token_table -c03cfce4 D kallsyms_token_index +c03cf804 D kallsyms_markers +c03cf89c D kallsyms_token_table +c03cfcb0 D kallsyms_token_index Huge chunk of symbols in tmp_kallsyms2.S are shifted by 0x20000 wrt tmp_kallsyms1.S (_sinittext and _einittext being among them). --- tmp_kallsyms1.S_ +++ tmp_kallsyms2.S_ -T __sched_text_start PTR 0xc0311e9e +T __sched_text_start PTR 0xc0311ea0 -T _sinittext PTR 0xc03b5000 +T _sinittext PTR 0xc03d5000 -T _einittext PTR 0xc03cc682 +T _einittext PTR 0xc03ec682 Gnu C 3.4.2 binutils 2.15.92.0.2 Linux C Library 2.3.4 Dynamic linker (ldd) 2.3.4
