Hi All
i've ubuntu8.10 kernel 2.6.27 installed in my system.
I've to debug the kernel using kgdb, for that i searched on net and found that kgdb is avaliaible only for 2.6.15 kernel source.
so i downloaded 2.6.15 kernel source and did everything to compile it (i used the config file from the kernel installed in my machine having kernel 2.6.27)but in the compilatoin it is giving me the error:

include/asm/mpspec_def.h:78: warning: packed attribute ignored for field of type unsigned char[6]
arch/i386/kernel/apic.c: In function smp_apic_timer_interrupt:
arch/i386/kernel/apic.c:1136: sorry, unimplemented: inlining failed in call to smp_local_timer_interrupt: function body not available
