Hey guys,

I have Asrock H110 BTC+ motherboards with Sandisk USB3 flash drives for SmOS. Lately I am getting a strange intermittent error the OS stops booting. Here is a short description of it:
....
usb usb2-port1: cannot enable. Maybe the USB cable is bad
usb usb2-port1: unable to enumerate USB device
usb usb2-port1: cannot disable (err = -32)
Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
 - Check rootdelay= (did the system wait long enough?)
 - Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! UUID= does not exist. Dropping to a shell!
...
(initramfs)

It seems to me USB module issue or kernel bug. I have switched to SSD via SATA and did not have the issue yet. Did any of you guys had the same issue? Fix?

I have multiple rigs out there still booting from USB thumb drive and would like to find the culprit and solution. Any help will be greatly appreciated.

Thank you
