If task is the task_struct of the process in question, on i386 task->thread->eip is the instruction pointer (what you mean by "pc" above I presume). Other processor state is in task->thread. See asm-i386/processor.h for i386. The registers are stored on the stack. See arch/i386/kernel/entry.S. Robert Love -- Kernelnewbies: Help each other learn about the Linux kernel.
