Works too. What is the difference (in my case)?

dmesg looks the same.

dmesg | grep -i aspm
[    0.761712] ACPI FADT declares the system doesn't support PCIe ASPM, so disable it
[    0.792916] ACPI _OSC control for PCIe not granted, disabling ASPM

Real Programmers consider "what you see is what you get" to be just as 
bad a concept in Text Editors as it is in women. No, the Real Programmer
wants a "you asked for it, you got it" text editor -- complicated, 
cryptic, powerful, unforgiving, dangerous.
