Bug Description
The machine goes into suspend but can't wake up from it. When inspecting /var/log/kern.log afterwards, no suspend-related messages are added to it at that time, while on my Dell Latitude E6400 which has working suspend there are. On the E6400 the first line that would show up is "PM: Syncing filesystems ... ", which is from the enter_state function in kernel/
int enter_state(
{
int error;
if (!valid_
if (!mutex_
On the M101z the function returns after mutex_trylock, while on the E6400 it carries on.
I then found out about the s2ram instructions at http://

noapic isn't sufficient to work around this: if I leave the machine suspended for a non-trivial amount of time (say more than a minute), it's again unable to wake up. In that case I also can't turn the machine off using the power button anymore, and have to disconnect the battery to restart.
