Some additional info: - a short self-test of the SSD has already completed without errors
- there was barely any memory usage while the bug occured, so it shouldn't be an out of memory issue - iotop shows always ~5 seconds of 99% I/O usage of the "cp" command at the top with nothing notable else going on, then ~8 seconds of ~50% usage of the "dmcrypt_write" command at the top with nothing else notable going on. This might be normal, I just mentioned it because the weird switching back and forth between those two looked a bit odd -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1682402 Title: Running I/O heavy operation (cp) inside terminal in X server session will lock up entire system while running it in a TTY works fine To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1682402/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
