I know this is realted to power problems, but Ive been using my empeg since January with the same PSU capable of 1.5A at 12V. Recently it has started to show the Failed to unmask IDE error on plugging in the power supply.
This is always after the empeg has been off overnight.
To fix it I just remove the power and replace, boots up no problems. Even if I remove the power for say an hour, it will boot up just fine.

Any ideas as to why this is happening?
I havent upgraded the kernel or hijack in a while, and last did so before this problem appeared.
Suggestions / fixes welcome!
