Hello,

When I try software suspend on my laptop it always returns to my running 
system after some time.
This is what's logged by the kernel:

swsusp: Basic memory bitmaps created
Stopping tasks ... 
Stopping kernel threads timed out after 20 seconds (1 tasks refusing to 
freeze):
 cryptd
Restarting tasks ... done.
swsusp: Basic memory bitmaps freed

I have no idea what's the problem, but if you tell me what I should do I can 
create debugging information and/or test patches.

I have my config attached, the kernel is 2.6.22-rc3

Maxi

Could you try this patch, please? It should help.

Herbert, is this right? If cryptd is going to be used for block devs,
the task should probably be PF_NOFREEZE (or whatever it is today)
instead.

Nigel

Probably.  However, I don't think this is responsible for the reported
problem because the code to use cryptd in dm-crypt hasn't been merged
yet :)

You have the cryptd Kconfig option in (at least in rc3) - presumably
Maximillian has been too keen and turned it on before you were ready :)
It does make sense for it to be the problem. Without PF_NOFREEZE set,
the refrigerator code will try to get it to enter the freezer, and
without the try_to_freeze(), it will just loop and freezing will fail.

Regards,

Nigel

OK that makes sense.  I'll apply your patch.

Please add '#include <freezer.h>' to crypto/cryptd.c for the patch to
compile.

FYI, I'm going to post a patch that will make this try_to_freeze() unnecessary,
but I don't think it'll make it into 2.6.22.

Greetings,
Rafael

I tried your patch, but when I apply it my kernel doesn't compile any more. I 
get these warnings/errors:

[...]
  CC      crypto/cryptd.o
crypto/cryptd.c: In function ‘cryptd_thread’:
crypto/cryptd.c:344: warning: implicit declaration of function ‘try_to_freeze’

You need to add '#include <freezer.h>' to crypto/cryptd.c .

Ah. You'll need to add #include <linux/freezer.h> near that start of
crypto/cryptd.c. Sorry for forgetting that.

I added the include line and now I could compile the kernel, but suspending 
still doesn't work.

swsusp: Basic memory bitmaps created
Stopping tasks ... 
Stopping kernel threads timed out after 20 seconds (1 tasks refusing to 
freeze):
cryptd
Restarting tasks ... done.
swsusp: Basic memory bitmaps freed

OK, this means that cryptd doesn't execute the try_to_freeze() for some
reason.

Please apply the appended patch on top of 2.6.22-rc3 and see if that helps.

Well, it looks like we have to fix this one separately.

Can you please tell me what to do to make cryptd run?

Well, there really isn't much I do. When I switched from 2.6.21 to 2.6.22-rc2 
I did a 'make oldconfig' and I enabled CONFIG_CRYPTO_CRYPTD because I thought 
it would be a good idea. I don't need cryptd,  I just enabled it. Now when I 
boot this kernel it seems like cryptd is automatically started.

I also tried building a kernel where CONFIG_CRYPTO_CRYPTD is disabled and 
there suspending does work fine.

If you build it as a module then just loading it should be sufficient.
If you have it built-in then it should always be there.

Let me know when you guys have a final patch.

The problem is more serious than I thought:

kthread_create() in crypto/cryptd.c line 302 doesn't return, so cryptd is stuck
in TASK_UNINTERRUPTIBLE all the time and it doesn't even execute one
instruction from cryptd_thread() [this happens on x86_64].

I've investigated this for a while, but I don't know why it happens.

Greetings,
Rafael

Sorry, I was wrong.

kthread_create() returns, but cryptd_thread() is not executed and the cryptd
process is stuck in TASK_UNINTERRUPTIBLE.

It can be fixed by replacing the kthread_create() with kthread_run().  Patch
follows.

Make cryptd actually run and mark it as nonfreezable.
