            Bug ID: 259748
           Summary: Loading mlx4en kernel module hangs
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: thj@FreeBSD.org

Loading mlx4en on CURRENT (main-n250453-7ac82c96fe7) hangs kldload. Pressing ^C
allows the module to continue and to load properly.

This happens from a shell and when loading the module using 'kld_list'

The mlx4en part of dmesg is:

mlx4_core0: <mlx4_core> mem 0xfce00000-0xfcefffff,0xe0000000-0xe07fffff irq 54

This happens on my Ryzen 3700X system, but happened previously on other
systems. 13-RELEASE doesn't have this problem
