I have a kind of opposite problem on an old Lenovo laptop where Windows boots just fine every time but any Linux distro I try randomly fails to boot with an ACPI error.

It's not a RAM issue though. AFAIK there's some bug in the UEFI/BIOS even on the latest version which Windows handles just fine but Linux randomly doesn't. I can boot Linux every time if I disable ACPI at boot but then I lose power management and battery percentage. Latest kernels (can't remember the version exactly, 4.somethingoranother) should handle the issue according to some forum posts I found but it doesn't for me.
