If you are using binary only graphics card drivers does the problem also 
happen without them never loaded at all?

I had a machine that would not suspend properly until some time part way 
through the 2.6.25 kernel. It might be worth reporting whether you have 
the same problem (perhaps by using a live cd) when you use a 2.6.26 or 
later kernel...

I do know that it *does* suspend fine *with* the binary driver, provided the SATA drive isn't in the docking station, and that the laptop has been suspending fine like this for several months / kernel revisions.

I have never tried suspending the laptop *without* the binary driver, and so have no idea whether the display will unsuspend correctly.

That's definitely not the case here.

I have just replicated the problem exactly without the fglrx module (ever) loaded at all, and using the very latest radeonhd DDX driver instead. So this really IS *just* to do with the SATA drive in the docking station.

Hi,

I have now migrated my laptop to the 2.6.26.5 kernel, and it is still failing to resume from "suspend to RAM" if the SATA drive is in the docking bay. I did notice the following in the dmesg log, which might be relevant:

ACPI: \_SB_.PCI0.IDE0.PRIM.MSTR: found ejectable bay
ACPI: \_SB_.PCI0.IDE0.PRIM.MSTR: Adding notify handler
ACPI: Error installing bay notify handler

I have raised this as bug #11604 at bugzilla.kernel.org.

Cheers,
Chris


      

Thinkpad T60p does not recover from Suspend when docked.

[Chris Rankin]

Hi,

I have a Thinkpad T60p with an "advanced dock" that contains an extra SATA drive, and I have noticed that when the extra drive is in the docking station then the laptop no longer recovers from Suspend. Remove the drive from the docking station and the laptop suspends and resumes OK again.

My user-space environment is Fedora 9, which automatically mounts the docking station's drive under /media when I login. However, it doesn't make any difference if I unmount this drive before suspending - the laptop fails to recover regardless.

I am running a 2.6.25.17-SMP kernel (for graphics card reasons), and can provide ACPI table dumps if required. Can anyone suggest anything to try, please?

Thanks,
Chris
