[Xen-devel] why I couldnt' use the prink statement in the do_memory_op function in the xen/common/memory.c file

["Wen.Tian" <tyd126723@xxxxxxxxxx>]

Hi, all

 

I use the prink to trace the xen code all along, but I find when I insert a printk statement in the do_memory_op function in the xen/common/memory.c file, the domain0 could not started, it always stop after the console driver inistiated .

 

I have tired the prinkt in the do_domctl hypercall, there is no such type of issue .

 

what's the issue might be?

 

Thanks for your response in advance.
