Comment 8 for bug 1705745

You might be thinking of https://bugs.launchpad.net/ubuntu/+source/linux-snapdragon/+bug/1591994 which was not dmi related. Or, if there was a dmi related one, it may also be because dmidecode was trying to read directly from a memory location rather than sysfs, because at least today, I don't see any dmi entry in sysfs on my dragonboard:

ubuntu@localhost:~$ ls /sys/devices/virtual/
bdi/ graphics/ misc/ sound/ usbmon/ workqueue/
block/ input/ net/ thermal/ vc/
bluetooth/ mem/ ppp/ tty/ vtconsole/
