Subject: Re: [PATCH v2] nvme/pci: Add DEEPEST_PS quirk for Lenovo N60z laptop

Sorry, please just don't merge this patch!!!

Just a few minutes after I sent this patch, right now (after I quiesced 
this lenovo n60z laptop for 10 hours),

its nvme disk crashed again! Just like before, nothing can wake it up 
except a reboot.

This is very surprising and it seems that only 'NVME_QUIRK_NO_APST' is 
the correct choice.

I'm sure that 'NVME_QUIRK_NO_APST' will not have the same problem, I 
have tested dozens of devices of the same model before.

I will send patch v3 to revert the code to its original state.
