Comment 3 for bug 76431

Hi, I am not using Ubuntu, but this might help in narrowing down / fixing this bug: I got the same message and failing suspend-to-RAM on a ppc embedded target with the pata_sil680 driver:

pata_sil680 0000:00:0c.0: suspend
ata1: suspend failed, device 0 still active
pci_device_suspend(): ata_pci_device_suspend+0x0/0x74() returns -16
suspend_device(): pci_device_suspend+0x0/0xac() returns -16
Could not suspend device 0000:00:0c.0: error -16

Kernel post 2.6.20 from powerpc.git. I posted a bunch of emails to all possible lists, see, e.g., http://lkml.org/lkml/2007/3/1/344, no replies so far... Here's the original patch, I think, that has introduced this test: http://marc.theaimsgroup.com/?t=115012763500002&r=1&w=2

Good luck
