Hi there,
I have a system with a S1200V3RPL Server Board in an Intel P4000S chassis, using the latest available FW version S1200RP.86B.02.01.0004.
There are also two raid controllers installed:
Controller #1: Intel RMS25JB080; FW version 13.00.66.00-IR
Controller #2: Intel RMS25KB080; FW version 17.00.01.00-IR
I have been testing Suspend-to-Ram (ACPI S3) and it initially worked ok, but this was because I was suspending for a short period, say 1, 2, 5 or 10 minutes and then resuming. During suspend, the power led flashes as expected. Even for a longer period say 1 or 2 hours, it works ok.
However, when I resume after a period of many hours, e.g. greater than 12 hours for example, the system seems to perform a full boot with the POST startup (beeps) etc. As you can imagine, this is a time-consuming and difficult problem for me to investigate the cause - I have tried suspending for long periods, e.g. 4, 5, 6 hours, and for these kinds of periods it resumes ok without the full boot. I have only observed the full boot problem for periods of over 12 hours (although I haven't done extensive testing, so it could be the case that a lower period will cause the problem, e.g. 9 or 10 hours).
What is the cause of this strange behaviour? I would have thought that suspend-to-ram would either be
a) fully and correctly supported, or
b) not supported at all (e.g. show an error message when attempting to suspend),
but not this strange situation where it is 'partially' working, depending on the time period (which is frustrating, because it makes me believe it is fully working, only to later discover that it is not, which is of no use to anyone).
Thanks
Alex.
