Have you checked the power supply? |

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. |

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. |

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. |

Just a suggestion... |
