That “disk” is a bit vague, so must assume it’s the DVD being deployed.
What happened was than I ran an upgrade from an alert that then asked for a restart, but when I restarted I got the same as the current problem: I got a blank screen and no apparent response. I then tried the previous version of the kernel and got the error message that turned out to be a symptom of the corruption on the btrfs partition.
So that is all after the update by DVD? The desktop notifier/updater (e.g KDE’s Apper, whatever) tells you updates are available, you make them, a restart is required (possibly the result of kernel update to latest 3.16.7-21…) and it failed.
Before we realised that it was a problem with the btrfs partition it was suggested to me that I should try upgrading using the latest .iso file on the openSuSE website, so that’s what I did. That, of course, did not solve the problem of the OS being loaded readonly, but that’s how, I think, this version of the kernel got installed.
Ah, here you address my question about the source of the working kernel (3.16.7-13.2): “the latest .iso file on the openSuSE website”. Well from the download page, it seems to be named “openSUSE-13.2-DVD-x86_64.iso”. We could assume that is the likely source of your working 3.16.7-13.2 kernel, or:
However, there is the recent suggestion from Carlos to try that rpm command in a terminal. You could also try firing up YaST on your system after placing the DVD in the drive (do NOT reboot), it should be picked up as a repo (if still in the repo list). Failing that, let me introduce you to the log at /var/log/zypp/history, where all package installations, updates, and removals are logged, dated and timed. Start from the end, working back, or use search/find on “3.16.7-13.2”.
Once we identify the source, the “rogue” vanishes ;).
