Comment # 17 on bug 1028575 from Mircea Kitsune

Thanks for the info! A llvm update sounds like something that might fix this
issue, let's hope llvm 4.0 does. If not, I don't know what the problematic
commit might be, so apart from safely doing a reversion we'd also have to find
that out. The system takes at least 3 days of uninterrupted uptime to even
slightly confirm the absence of this freeze, so testing it is also hard.

One of my suggestions in the other bug report was dumping my package
installation history over the last month. That way we could see which package
changes match my time line (problem first starting around 08-03-2017, stopping
near 22-03-2017, then happening again on 02-04-2017). However there doesn't
seem to be a zypper command to dump package installation history over a fixed
amount of time... if anyone knows of one please let me know.
