I updates /usr/src to r355452, and updated by kernel and
world. Upon rebooting, verbose boot messages susgests
the system is hanging when USB starts to attach. With
the 3-week kernel verbose boot shows:
...
pcm4: <Realtek ALC889 (Rear Digital)> at nid 30 on hdaa1
pcm4: Playback:
pcm4: Stream cap: 0x00000005 AC3 PCM
pcm4: PCM cap: 0x000e05f0 16 20 24 bits, 32 44 48 88 96 192 KHz
pcm4: DAC: 6
pcm4:
pcm4: nid=30 [pin: SPDIF-out (Grey Jack)]
pcm4: + <- nid=6 [audio output] [src: pcm]
pcm4:
pcm4: Mixer "vol" -> "none": child=0x00000010
pcm4: Mixer "pcm": parent="vol"
pcm4: Soft PCM mixer ENABLED
pcm4: Playback channel set is: Front Left, Front Right,
pcm4: Playback channel matrix is: 2.0 (unknown)
usbus0: 5.0Gbps Super Speed USB v3.0
usbus1: 12Mbps Full Speed USB v1.0
...
end with a prompt on the console. With today's kernel,
boot is hung after the last pcm4: message and no usbus0
is displayed.
The booting kernel/system is a
% uname -a
FreeBSD 13.0-CURRENT #1 r354658: Wed Nov 13 11:23:32 PST 2019, amd64
Again, the failing kernel is r 355452
