Suspend was working fine, but suddenly it's stopped working.

When I try and suspend it drops me to tty1 and says nothing. I can switch back to tty7 and continue working in X. In /var/log/pm-suspend.log it says "s2ram: symbol lookup error: s2ram: undefined symbol: LRMI_base_addr".

This happens when suspending from GNOME or from the command line.

Any ideas?

Thanks

If it just stopped working 'suddenly' then something must have changed either software or hardware-wise with the system.
Have you installed or deleted any packages or libraries?

In a root console, try this:

echo -n mem > /sys/power/state

and see if it suspends to ram properly. If it does, then something has changed with your s2ram tool or its dependencies (if any) so maybe reinstall/rebuild it.

If this doesn't work, see above (about whether you installed, removed, or changed anything) and undo whatever changed.

Best of luck

Thanks, that puts it to sleep.

I've got an identical computer which is running Debian Sid also. Both are up-to-date and that doesn't have this problem. It's very strange. Yes I install updates every day or so but it has only affected this computer, not the other one. I can't think of anything that I have done that would have caused this.

I'll try and reinstall the uswsusp package (I think that is the s2ram/disk commands) and see if that makes any difference.

Reinstalling didn't work, so I tried removing uswsusp and now it works! It didn't remove any dependencies. Maybe I installed something on this laptop (which I didn't on the other) that put this package on here. I'll file a bug report against this.
