System: NetBSD space-truckin.duskware.de 9.99.31 NetBSD 9.99.31 (GENERIC) #30: Tue Dec 31 14:55:51 CET 2019 martin%seven-days-to-the-wolves.aprisoft.de@localhost:/work/src/sys/arch/evbarm/compile/GENERIC evbarm
Architecture: earmv7hfeb
Machine: evbarm
>Description:

After an ATF test run this machine ended up with one cpu being
busy 100% and a h_ps2_strings process hanging. Unfortunately
attaching gdb is a kernel kill in -current, so no more
information on that process.

>How-To-Repeat:

cd /usr/tests && atf-run
