Somebody in the thread at some point said:
| Hey,
|
| Graeme and me see further resume issues with the gta02. After a five
minute
| sleep the device is not waking up.
|
| My magic printascii tells me:
|
| h i2c-adapter_ah_ijkg
| h i2c-dev_ah_ijkg
| h pcf50633_ab
|
|
| which means it is hanging in the platform_driver resume method. i2c was
| supposely initialized already. I will take a further look tomorrow.

Interesting news.

Take note of ./drivers/i2c/busses/i2c-s3c2410.c:

static int s3c24xx_i2c_doxfer(struct s3c24xx_i2c *i2c, struct i2c_msg
*msgs, int num)
{
	unsigned long timeout;
	int ret;

	if (i2c->suspended) {
		dev_err(i2c->dev,
		    "Hey I am still asleep (suspended: %d), retry later\n",
		    i2c->suspended);
		ret = -EAGAIN;
		goto out;
	}

I added this as a palliative for a previous resume ordering crash (that
did not depend on suspend time)
