Regression from 7627a0edef54 ("ata: ahci: Drop low power policy board type") on reboot (but not cold boot)

Hi Mario et al,

Eric Degenetais reported in Debian (cf. https://bugs.debian.org/1091696) for his report, that after 7627a0edef54 ("ata: ahci: Drop low power policy board type") rebooting the system fails (but system boots fine if cold booted).

His report mentions that the SSD is not seen on warm reboots anymore.

Does this ring some bell which might be caused by the above bisected[1] commit?

#regzbot introduced: 7627a0edef54 #regzbot link: https://bugs.debian.org/1091696

What information to you could be helpful to identify the problem?

Regards, Salvatore
