From: Ray Bryant It looks like the 2.6.0 lockmeter patch has lost the configuration menu entry to enable lockmeter on ia64. This is true of both 2.6.0-test10-mm1 and 2.6.0-test11-mjb3. (Martin appears to pull this from your tree.) Below is the trivial patch to fix this. With this change it appears to work fine on Altix, at least. arch/ia64/Kconfig | 7 +++++++ 1 files changed, 7 insertions(+) diff -puN arch/ia64/Kconfig~lockmeter-ia64-config-fix arch/ia64/Kconfig --- 25/arch/ia64/Kconfig~lockmeter-ia64-config-fix 2003-12-16 23:11:32.000000000 -0800 +++ 25-akpm/arch/ia64/Kconfig 2003-12-16 23:12:16.000000000 -0800 @@ -670,6 +670,13 @@ config DEBUG_INFO Say Y here only if you plan to use gdb to debug the kernel.
