Call traces have been observed running different tests that involve aborts and setting the rrq active flag. The lpfc_set_rrq_active routine is doing a mempool_alloc under the soft_irq processing level. When the mempool needs to get a new buffer from the free pool and has to wait for memory to become free it will check the flags passed in on the alloc and dump the stack if the thread is running in interrupt context. Replace the GFP_KERNEL flag with GFP_ATOMIC so that the memory allocation will not attempt to sleep if there is no mem available.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
