Can you try offline cpu, suspend/resume, attempt to online? Did this with no problems. Put CPU1 offline, STD'ed, resumed, checked whether it's offline, put it back online. No problems. Performed several consecutive offline/online cycles - no problems so far.

Performed several tests: 1. o. disconnected AC power o. put CPU1 offline o. STD/resume o. checked CPU1 state -> put it back online 2. o. on battery o. put CPU1 offline o. STD o. connected AC power o. resume o. checked CPU1 state -> put it back online 3. o. on AC power o. put CPU1 offline o. STD o. disconnected AC power o. resume on battery o. checked CPU1 state -> put it back online in all cases everything works good.

In http://en.opensuse.org/S2ram, there is documentation to find the options needed for your machine. Please try this also from the text console. In http://en.opensuse.org/Pm-utils, there is documentation on how to make the system use the options you found out with the previous step. If you post the output of "s2ram -n" and the needed options into this bug, i will also add your machine to the whitelist, so that is works out of the box in the next release. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Second core goes offline hardly after resume from disk, even with latest factory update to 2.6.27.7-6-default.

There are a couple of things you can try to debug this further, but for this purpose you'll have to be able to compile and install the kernel yourself.

With 2.6.27.7-3-default every STD/resume cycle led to problem. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
