During systemd reboot sequence network driver interface is shutdown by e1000_close. The PCI driver interface is shut by e1000_shutdown. The e1000_shutdown checks for netif_running status, if still up it brings down driver. But it disables msi outside of this if statement, regardless of netif status. All this is OK when e1000_close happens after shutdown. However, by default, everything in systemd is done in parallel. This creates a conditions where e1000_shutdown is called after e1000_close, therefore hitting BUG_ON assert in free_msi_irqs.

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.
