Even if messages is DEBUG, I assume condition is unusual (otherwise we 
would not need any message in the first place).

This is Dell XPS M1330 with ICH8M:

00:1f.1 IDE interface: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) 
IDE Controller (rev 02)                                                                 
        Subsystem: Dell Device 0209                                            
        Kernel driver in use: ata_piix                                         
        Kernel modules: ata_piix, pata_acpi, ata_generic, piix, ide-pci-
generic
00:1f.2 SATA controller: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) 
SATA AHCI Controller (rev 02)                                                         
        Subsystem: Dell Device 0209                                            
        Kernel driver in use: ahci                                             
        Kernel modules: ahci                                                   

Every time I do to sleep I get:

PM: Entering mem sleep

ata_piix 0000:00:1f.1: PCI INT A disabled

...

Otherwise there are no negative effects as far as I can tell.
