>Description:
booting with dhcpcd=YES, with no cable plugged into my wm0, it
periodically spams dmesg:

[  1152.784855] wm0: device timeout (txfree 4032 txsfree 0 txnext 76)
[  1176.035005] wm0: device timeout (txfree 4032 txsfree 0 txnext 79)
[  1201.285172] wm0: device timeout (txfree 4032 txsfree 0 txnext 76)

until `ifconfig wm0 down`.

It causes audio skipping until the ifconfig down,
presumably due to a spike in system load.

Subject: PR/56478 CVS commit: src/sys/dev/pci
Date: Fri, 5 Nov 2021 05:52:50 +0000

 Module Name:	src
 Committed By:	msaitoh
 Date:		Fri Nov  5 05:52:49 UTC 2021

 Modified Files:
 	src/sys/dev/pci: if_wm.c

 Log Message:
 Fix a bug that device timeout still happens on ICH/PCH. Fixes PR kern/56478.

  - if_wm.c rev. 1.695 for PR kern/40981 still had a problem. The workaround
    flag was unexpectedly cleared when a cable is not connected, SIOCINITIFADDR
    was called, or if_init was called. Fix it.
  - Add debug printf()s.
