Hi *,
On my 64MB notebook I get the following message, when going swsusp:
..
swsusp: Need to copy 15526 pages
swsusp: Not enough free memory
Error -12 suspending
..
# free
total used free shared buffers cached
Mem: 62760 59884 2876 0 3828 16052
-/+ buffers/cache: 40004 22756
Swap: 200804 30316 170488
If I end all apps but the XServer it works. I've allready added some
more swapspace, but that didn't help. So, how much memory will I need
for a successful suspend or better (since i can't stuff any more into
it) is there a way to minimize the amount needed?

swsusp needs to be able to free half your memory to be able to suspend. I
don't know it intimately, but you may well be failing to do this. Being
completely biased (and not unwilling to admit it!), I'd suggest you try
Suspend2 (www.suspend2.net). It doesn't have such a limitation.
Regards,
Nigel

Thanks for this hint. However, I'm using ck's patches and having errors
compiling sched.c. Just took a quick look: I don't think I can get them
working together. The rest of the suspend2 patch (for 2.6.15.1) seems
to apply fine to 2.6.15.4 also (Not much changes IIRC).

http://iphitus.loudas.com/archck.php contains both Con's patches and Suspend2.

You're welcome ;) If you have any further problems, feel free to email again.
Better still, try the Suspend2 site and mailing lists - we've got some really
good docs and really helpful users. There's also an irc channel on Freenode.

Nigel

Actually suspend2 has exactly the same limitation. If more than
half memory is occupied by something else than disk caches,
you loose in swsusp and suspend2.

128MB should be enough for you. Or try modifying try_to_free memory routine to
retry shrink_all_mem few more times, with schedule() in between...

Swap? 128M was my first attempt -- OOM when the box was heavily loaded.
IIRC no effect on swsusp - there are 64M Ram + 2M Video + Kernel + X?.
The reason I did it were some google results talking about free pages.
There were some solutions talking about adding swap.
(Ram? Would be the way to go, but it's fully loaded.)

Uhh. I don't think this will be a good idea /me ha[ck|rm]ing good ol'
linux source. ;-)

RAM. No ammount of swap will help you.

It should be easy. It is quite hard to loose much data this way ;-).
