Kai-Heng, did you run the command as root? Otherwise you may want to `sudo su` and run the loop or "prime" your sudo by running `sudo echo` (to get prompted for you password once) and then use the same loop but instead of `> /path/to/file` use `| tee /path/to/file` and see if you get different results.
I will bookmark this to test after my next restart, as I'm seeing the same issue on boot, and I don't know that changing the system hardware test from Automatic to Thorough or Quick in the BIOS will make a difference. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1697395 Title: Thunderbolt devices don't work if connected during boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1697395/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
