Thanks, that's always nice to hear. :-)

Yeah, so this is a one-time, exceptional thing as *everything* else
works, see comment #68 and the ones before it. We tested it on
everything we could get our hands on and it was fine. I've been running
those changes for a while with the upstream kernel to make sure they're
good to go before backporting them to oS.

But, as it happens according to Murphy, only those boxes are funny. And
I'm working on a solution, it just takes time.

But I certainly understand you - a system shouldn't break from an update
but it seems we've poked the beast too deep this time :-)

Yeah, paint is still wet about the whole issue but once I have concrete
info, I'll put it here.

Right, so early microcode update wasn't working on AMD at all. I've
fixed it upstream and we pulled it into openSUSE because it is a Good
Thing(tm) to have. And this issue was unexpected.

No need, the other two messages you pasted are enough. It basically
shows that 13.1 did late microcode update (which has always worked fine
but was happening too late) and 13.2 didn't update at all.

The version 0x010000af is the one which your system gets from the BIOS
and 0x010000c8 is the latest one which AMD distributes.

Thanks for now and stay tuned.
