After upgrading my completely working copy of OpenBSC

git version, it stopped working and is stating an error of "DLP
FAILED" and "DISABLED RSP" and the BTS seems to just reboot. This
process repeats over and over. Unfortunately I do not have the
version/commit of the one it was previously on, however it was likely
from a month or two ago. To troubleshoot that my equipment wasn't at
fault, i restored a VMWare snapshot I took before upgrading and it
worked perfectly.
If you have that vm snapshot, you can simply go back to that snapshot
and obtain the version information of openbsc at that time. Theres a
'show version' command in the VTY. The first line should give you
version information.
I think what you may experience is the fact that maybe nobody actively
involved in the development of OpenBSC might still be using nanoBTS at
this time. Given that ip.access has never supported this project in any
way by themslves either, regressions might have been introduced
inadvertently over time.
I don't have time to debug this myself, but I would be more than happy
to try to fix it once the detailed issue / commit causing the problem
has been established. The later should be done by those users
interested in continued nanoBTS support, as they have a natural interest
in that matter.
Also, it would make sense to incoude in your bug report pcap files of
the OML for both the working vs. non-working case

Just as I see this: Are you sure your BTS actually supports the
transmission of SI2 quater? The version from one month ago couldn't yet
have had this feature, could it? If so, then please make sure you test
with identical configuration file when comparing old and new version.
