<![CDATA[HP DC7800 Not working with ACPI=off]]>I mistakenly reported I was able to successfully image a DC7800 by adding the host to a group that had a kernel parameter “acpi=off”. It turns out I was mistaken. It was a DC7900.

The DC7800 can make it to the fog menu and successfully register. However, when trying to deploy or capture I get this

NO GROUP

IN GROUP with “acpi=off”

Is there another kernel parameter I need to use?

In the mean time, I had to install an older kernel in order to image it.

I can try that later this week. If manually setting acpi=off in the host configuration kernel parameters field works then wouldn’t that mean the kernel parameter field for groups does not work?

I wish this place would get rid of those awful DC 7800’s

Manually set it in the host configuration kernel parameters field. That should solve the stall detected issue.
