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. CC: xe-kernel@external.cisco.com Signed-off-by:
