So I have a HP Microserver which was running 14.X Ubuntu for ages. Due to adding a new disk and a lack of space in root on the system, I decided to re-install from scratch using 16.04.
Kernel currently is 4.10.0-42-generic That was successful. But since then, 9 times of 10 the system does not boot.
I get these errors
"ERST: failed to get log address" in log message.
"BERT: Can't request iomem region 0000000077fab650-0000000077fab6aa3"
"ata2.00: failed to enable AA" I've no idea what those mean. It then enters "emergency mode"

A bit of googling suggested a BIOS update to the Microserver which I did. Hasn't helped. I can usually get the system to boot with a combination of rebooting (multiple times) and/or power on/off. But this is not really acceptable for a reliable server. I don't think the issue is related to the new HDD (which is not the boot disk) as if I remove it, I still have the same issue.

Anyone able to point me to what these errors mean and how to fix the issue? I'm considering downgrading back to 14.X Thanks
