when there's an error in 'ncq mode' the host has to read the ncq error log (10h) to clear the error state. however, the ccb that is setup for doing this doesn't setup the ccb so that the previous state is cleared. if the ccb was previously used for an IO n_elems is set and pm8001_ccb_task_free() treats this as the signal to go free a scatter-gather list (that's already been freed).

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.
