It's been a while since I needed to do a sysrq t, but I don't recall seeing every RIP being cryptic like this, and then also with a Bad RIP value message.
[ 43.758824] RIP: 0033:0x7ffb472e779f [ 43.758826] Code: Bad RIP value.
I see it with both 5.3.0-0.rc3.git0.1.fc31.x86_64+debug 5.2.6-200.fc30.x86_64
I also tried installing kernel debuginfo, but it's the same. I have no idea when the last time it was I saw something different so maybe this is just the new normal.
