System: NetBSD seven-days-to-the-wolves.aprisoft.de 9.99.49 NetBSD 9.99.49 (GENERIC) #356: Mon Mar 9 10:32:52 CET 2020 martin%seven-days-to-the-wolves.aprisoft.de@localhost:/work/src/sys/arch/amd64/compile/GENERIC amd64
Architecture: x86_64
Machine: amd64
(this is an older kernel, for obvious reasons)

>Description:

Trying to boot an amd64 GENERIC kernel as of a few minutes ago stops midway
on this machine. Usual output (see full dmesg below):

[   2.8817516] uhub8 at usb8: NetBSD (0000) EHCI root hub (0000), class 9/0, rev 2.00/1.00, addr 1

[   3.1118215] ahcisata1 port 0: device present, speed: 6.0Gb/s
[   3.9820640] ehci1: handing over full speed device on port 1 to ohci1
[   4.7022652] wd0 at atabus2 drive 0

The last line or sometimes two last lines do not show up with -current.
Can break into ddb, all cpus in the idle loop.
