The driver may sleep under a spinlock. The function call path is: qedi_cpu_offline (acquire the spinlock) qedi_fp_process_cqes qedi_mtask_completion qedi_process_tmf_resp kzalloc(GFP_KERNEL) --> may sleep To fix it, GFP_KERNEL is replaced with GFP_ATOMIC. This bug is found by my static analysis tool(DSAC) and checked by my code review.
