Hi, Just tried to build 2.6.21-rc5-rt6 and it is failing on build time. ... kernel/sched.c: In function ‘__schedule’: kernel/sched.c:3830: error: ‘print_functions’ undeclared (first use in this function) kernel/sched.c:3830: error: (Each undeclared identifier is reported only once kernel/sched.c:3830: error: for each function it appears in.) ... arch/i386/kernel/apic.c: In function ‘smp_apic_timer_interrupt’: arch/i386/kernel/apic.c:589: error: invalid lvalue in assignment arch/i386/kernel/apic.c:608: error: invalid lvalue in assignment ... Just to let you know that -rt5 was doing fine with very same .config .
