Comment 24 for bug 1697395

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.
