IBM R50p suspend issue (Suse)
 
Hi,

I am having issues with the suspend on Suse9 (SP1) on IBM R50p. I am able to successfully suspend the system, but on powering up, it seems like its trying to power on but there is no display. I have to hard boot the system to bring back the normal functionality.

Your suggestions are appreciated

Thanks.

What the heck is the (SP1?)... suse doesnt have service packs...

Anyway...
First, upgrade to 9.2 so you have a newer version of everything and possibly it will work.
But in the meantime, follow the advice that suse itself gives you. Suspend is "EXPERIMENTAL." Hence, if it didn't work when you tried it, stop trying it.

Yes, running the latest version on your lappie is good when it comes to power management. Your success may depend on whether you use APM or ACPI as your method.

With the recent kernel 2.6.8 and on, ACPI is probably the preferred method. However, for best result you may have to recompile your kernel and applying an ACPI patch. Check these forums and Google on how to recompile kernels if you've never done it.

Also, ACPI may require you to some other tricks in order to get your laptop to resume successfully (often involving graphics and USB). Since you have a ThinkPad you really, really want to search the archives of, and probably join, the Linkux-ThinkPad mailinglist. I can assure you that you are not the only person running Linux on a ThinkPad...

Good luck,

How do you get suspend to work? :-)

If the question was aimed to me, all I do is to run kernel 2.6.10 without any special ACPI patch. I also unload the USB modules (ehci_hcd and uhci_hcd) before suspending (but IIRC this may not be needed with that kernel). With kernel 2.6.8.1 I applied the ACPI patch.

When I try to suspend, my screen goes black - and I get this:

Code:

PM: Preparing system for suspend
Stopping tasks: ====================================================|
PCI: Setting latency timer of device 0000:00:1d.7 to 64
Could not suspend device 0000:00:1d.7: error -5

(My appologizes to Pico_01 for what seems to be a hijacking of the thread...)

If you type the command 'lspci' you can see what device that corresponds to the address 0000:00:1d.7. That's where you want to start your troubleshooting. If that is the USB controller och PCMCIA controller or something loadable, try to unload the related modules (rmmod) before suspending, and reload them (modprobe) when resuming.

Good luck and happy new year,
