System crashed due to a hard lockup at lpfc_els_timeout_handler+0x128. The els ring's txcmplq list is corrupted: the last element in the list does not point back the the head causing a loop. Issue is the els processing path for sli4 hbas are using the hbalock instead of the ring_lock for removing elements from the txcmplq list. Use the adapter SLI_REV to determine which lock should be used for removing iocbqs from the els rings txcmplq. note: the future refactoring will address this so that we don't have this ugly type-based lock code.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
