12 Have you checked the power supply?

14 I don't use a diskless setup but last year (nah, maybe many years ago) I
15 had this strange resume problem after suspend. As in, I'd wake the
16 machine and it'd sit there with a blinking text cursor in text mode,
17 quite stuck. I am pretty sure I posted about it on the list here.
18
19 It turned out that when my machine was running the power supply was
20 fine. However, when I suspended it, the 5V rail would bleed voltage. So,
21 I discovered if I resumed within, say, 5 minutes after suspending my
22 machine it would wake normally. After that though, I'd get the blinking
23 cursor and it would hang resuming.
24
25 I confirmed that the 5V rail was bleeding voltage when in suspend with
26 my voltmeter. It turned out to be bad capacitors in the power supply.
27
28 Just a suggestion...
