Double suspend to ram doesn't work on acer aspire 5720g

[Maxim Levitsky <maximlevitsky@gmail.com>]

Hi,

If I suspend system to ram twice, the system hangs on resume.

Otherwise system suspends fine.

I can do the following:

suspend to disk
suspend to disk
suspend to ram
suspend to disk
suspend to ram
suspend to disk
suspend to disk.

but not this:

suspend to ram
suspend to ram.
<-> hang


Before I start digging deeper, are there patches floating around that 
could fix this issue?

(I use latest linus -git kernel)

(I tried to use minimal system and got same results)

Have to confess that I use nvidia binary drivers, and without them
video doesn't resume, but I did test this issue without them, and
got same results.

(after first suspend to ram video didn't resume, but I was able to 
control the system with keyboard, and I then put it to sleep again, and 
on resume, system didn't respond.)

Best regards,
