huh, entered softirq %u %s %p with preempt_count %08x, exited with %08x?

这段话可能是来自 Linux 内核的调试信息。其中 %u %s %p %08x 都是占位符，用于打印不同类型的变量值。其中，“%u”表示一个无符号整数，"%s" 表示一个字符串，"%p" 表示一个指针，"%08x" 表示一个 8 位十六进制数。

这段信息的意思是：内核中的软中断被触发了，同时打印出了相应的信息。在进入软中断时，记录了当前的抢占计数器值（preempt_count），并在退出时再次记录了这个值。这个值用于确保在处理软中断期间不会被抢占。
