I see this issue on my old Soekris net5501s as well. Using Barry's data
from above regarding dates I can confirm that the Janusary 6th snapshot
on hostserver.de's archive works, but trying to install the January 7th
snapshot results in the init message rolling until the system is power
cycled:
init: single user shell terminated, restarting
If I boot the January 7th bsd (with the January 6th userland) I see
the same behaviour as Barry reported if he upgraded using an older
bsd.rd, ie it gets to mounting the drives and then blows up:
root on wd0a (14df1105db104991.a) swap on wd0b dump on wd0b
init: /bin/sh on /etc/rc terminated abnormally, going to single user mode
Enter pathname of shell or RETURN for sh:
# ls
.cshrc boot bsd.rd home sys
.profile bsd bsd.upgrade mnt tmp
altroot bsd.booted dev root usr
bin bsd.jan7 etc sbin var
init: single user shell terminated, restarting
Enter pathname of shell or RETURN for sh:
# reboot
Here is dmesg with January 6th snapshot installed (where everything
works)
