| |
Hi all,
with 2.6.31 'crash' on x86_64 falls flat on its face as the '_end' symbol is missing from the System.map file.
The culprit is commit 091e52c3551d3031343df24b573b770b4c6c72b6, which moved the '_end' symbol into it's own section. Apparently this causes kallsyms to not reference it properly.
So either we'd need to revert part of the patch to not include _end in it's own section:
diff --git a/arch/x86/kernel/vmlinux.lds.S b/arch/x86/kernel/vmlinux.lds.S index 59f31d2..1422df5 100644 --- a/arch/x86/kernel/vmlinux.lds.S +++ b/arch/x86/kernel/vmlinux.lds.S @@ -376,9 +376,7 @@ SECTIONS __brk_limit = .; } - .end : AT(ADDR(.end) - LOAD_OFFSET) { - _end = .; - } + _end = .; /* Sections to be discarded */ /DISCARD/ : { or someone has to fixup kallsyms. But this is far beyond my comfort zone.
