Hello rt-list! I have compiled Kernel 2.6.33.7 with rt-patches and arm-patches (http://maxim.org.za/AT91RM9200/2.6/2.6.33-at91.patch.gz) for an ARM AT91SAM9260. The system stops running at Freeing init memory I traced this down to the file linux-2.6.33.7/arch/arm/kernel/sys_arm.c , where an assembler command does not return. Check this code snippet: printk("HELLO 1\n"); asm( "add r0, %0, %1\n\t" "mov r1, %2\n\t" "mov r2, %3\n\t" "bl memmove\n\t" /* copy regs to top of stack */ "mov r8, #0\n\t" /* not a syscall */ "mov r9, %0\n\t" /* thread structure */ "mov sp, r0\n\t" /* reposition stack pointer */ "b ret_to_user" : : "r" (current_thread_info()), "Ir" (THREAD_START_SP - sizeof(regs)), "r" (®s), "Ir" (sizeof(regs)) : "r0", "r1", "r2", "r3", "ip", "lr", "memory"); printk("HELLO 2\n"); "HELLO 1" can still be read, "HELLO 2" never appears. Any idea, what could be the problem?
