If I manually suspend for up to say 10 seconds, they resume just fine.
Have you checked the power supply?
I don't use a diskless setup but last year (nah, maybe many years ago) I
had this strange resume problem after suspend. As in, I'd wake the
machine and it'd sit there with a blinking text cursor in text mode,
quite stuck. I am pretty sure I posted about it on the list here.
It turned out that when my machine was running the power supply was
fine. However, when I suspended it, the 5V rail would bleed voltage. So,
I discovered if I resumed within, say, 5 minutes after suspending my
machine it would wake normally. After that though, I'd get the blinking
cursor and it would hang resuming.
I confirmed that the 5V rail was bleeding voltage when in suspend with
my voltmeter. It turned out to be bad capacitors in the power supply.
Just a suggestion...
