resume failing on ATA controller

resume failing on ATA controller

[Dave Airlie]

Hi,

I've got an HP 2510p with a 965 mobile chipset and ICH8, lspci is at

http://people.freedesktop.org/~airlied/hp2510p/hp-lspci-vv.txt

Resume is failing on the hard disk resume by the looks of it (no video
to prove it..) but I've rmmod nearly everything and my network
interface comes back and I can ping it but anything that tries to
access the disk looks stuck...

I also know someone running the same laptop using drivers/ide drivers
whose suspend/resume works properly....

I'm running the latest Fedora rawhide kernel based on -rc3-git7

Dave.

Do you use power-on password by chance?

libata doesn't enable ACPI support by default. It needs the libata_acpi 
option enabled at boottime (libata.libata_acpi?) in order to execute the 
ACPI methods that HPs seem to need to resume properly. With that change, 
mine works fine.
