Hi all: I would like to deliberately cause a kernel stack dump when the kernel is in softirq. Is it possible to do this? I have used the sysrq technique. However, the sysrq just dump all the process context when the magic key was pressed. In ksoftirqd, there are only two callstack traces in sysrq print result. I checked that value in objdump of vmlinux and found that it locates in arch_kernel_thread and end up in schedule(). Ksoftirqd manual mentions that ksoftirqd executes in process context only when there is already a softirq when the incoming one is registered(triggered), so the softirq are rarely be traceable when they are not in process context. Could you give me another technique to trace the call stack without modifying the code to panic()?
