You need the information in the panic message and trace. If you want to help get the problems with those machines tracked down, you need to get that information, maybe take a photo and type it in from there. If the panic message itself has scrolled off "show panic" should show it again. The only way disabling ACPI is helpful, is if the machine saves the dmesg buffer between boots, then you may be able to get the panic, boot -c, disable acpi, and save the information. ACPI should not be disabled on modern machines, they are not meant to work that way.
