Precision 3530 Bios update 1.11.1 broke Ubuntu 18.04 suspend

Hi,

On a Precision 3530, the bios update from 1.10.1 to 1.11.1 broke Ubuntu 18.04 suspend to RAM and made booting unreliable had to try 2-3 times each time before a successful startup.

I reverted to 1.10.1 with a USB stick and Latitude_5X91_Precision_3530_1.10.1.exe on it. It is all fine now.
Am I the only one?
