It appears to be worse with 3.7-rc1. The machine basically locked up a few moments after inserting the stick. First time I was on some tty and I saw lots of backtraces flowing by the process of which the BTRFS on /, which resides on an unrelated internal Intel SSD 320, was switched to read only. There have been pauses between backtraces. Second I was in KDE session which basically locked up soon as well. No mouse pointer movements where possible, no switching to tty1. I only have the last part of the backtrace of the first occurence as photo. Nothing was saved on SSD. I do not want to go an earlier 3.7 version than rc1 on this production machine. I can try rc2 tomorrow. How to proceed? With 3.7-rc3+somegit I was at least able to save out some dmesg output to the SSD before I rebooted the machine. I can try to get some longer backtrace this way. Oh, I see I have a dmesg > file that actually made it to SSD. This one is a tiny bit longer than the first one. Attached. The screenshot of shortly before I rebooted the machine is in [1]. That was some seconds after the BTRFS read only part slipped by. These are from the same, first occurence. I wonder that this apparently hasn´t been reported already. It may be configuration specific. I attached config file. It was same for plain rc3 and just with some f2fs options added for the f2fs kernel in my first post.
