The workqueue hfi1_wq is destroyed in function shutdown_device(), which is called by either shutdown_one() or remove_one(). The function shutdown_one() is called when the kernel is rebooted while remove_one() is called when the hfi1 driver is unloaded. When the kernel is rebooted, hfi1_wq is destroyed while all qps are still active, leading to a kernel crash:
I was under impression that kernel reboot should follow same logic as module removal. This is what graceful reboot will do anyway. Can you please give me a link where I can read about difference in those flows?
Thanks
