Lurking no longer.... finally registered to try to keep this thread alive. First, please allow me to catch up.
In the last few days or so, I noticed I've been experiencing the EXACT same issues as the OP aena9200.
I am using win7 64 bit and recently my machine can no longer hibernate for a second time after a clean boot (after a clean boot it can hibernate but then it cannot after a resume). I noticed Event 45 in the event viewer and it does not make any sense. I tried to hibernate from the command line but I am getting a message "not enough storage is available to process this command.(8)". When the hibernation fails I got back to the login screen (as if I locked the station).
The only difference on my end is that it dumps me back to the desktop rather than the login screen due to my preferences.
It should be noted that the OP and I are apparently using completely different motherboards and I am running a RAID array where they were not. Furthermore, it should also be noted that I just installed Win7 x64 Ultimate about 2 weeks ago. I have not had a single BSOD since that point and unless I missed something, my event logs support that claim.
That was the only relevant solution I found online, but again it did not help with my problem. I have just the bitlocker driver in this entry (dumpfve) and even removing it did not help.
Dude, just to make it easier, I am not a newbie so, I have already searched online and tried all the common things. This is why I was asking for some insights i.e. some other uncommon places to start looking into and this is why I was pretty sure posting the events won't help since there is nothing suspicious there. So, again other than the event 45 and the message I get when I hibernate from the command line, nothing is out of the ordinary.

Seems I traced your footsteps as you have tried all this. I will reach out for help to see about other possible solutions.
It appears I was walking in those same footprints before I even found this thread. Again, as with aena9200, the only listing in that registry key is for BitLocker (which I don't have enabled on my machine).
For posterity's sake I think I figured out what the problem is, it is one of many problems caused By Daemon tools. Apparently it happens when daemon tools is installed, for what ever reason it messes with hibernation and some how causes this error?
Heres a link to the information:
Event ID: 45 Source: Ftdisk
Then i went hunting through the copy of the files uploaded, specifically the list of drivers and low and behold Daemon tools is installed.
I would be somewhat surprised if this was the issue. The link you provided is for the situation where Event 45 is thrown with Ftdisk as the source. In both my and the OP's case, volmgr is the source. Additionally, I do not have Daemon Tools installed.
What I can add...
The only seemingly relevant errors in my system event logs are all Event 11 - 'The driver detected a controller error on \Device\Harddisk[X]\DR[Y]'. As far as I can tell, the RAID array is functioning normally aside from these entries. Admittedly, I'm running a much updated version of the Intel Rapid Storage Technology driver than I was prior to updating to Win7 x64 so there may be cause to suspect that driver. However, there seems to be little if any correlation between those errors and the Event 45 errors. Also, as I mentioned before, the OP was not running a RAID setup.
QUICK UPDATE: I started getting a feeling a drive in my array was failing and not being detected but after looking at things closer, I've realized that all the Event 11 errors are pointing to removable drives that are/were attached. This seems to further the theory the two events are unrelated.
Despite all the compatible RAM I own passing Memtest86, I wasn't able to get Windows + SP1 to install properly until I removed a certain two sticks from my system. As a result, I'm running on only 2 Gigs at the moment. I may swap out those sticks for the other 2 Gigs I have lying here and see what happens but I'm afraid that may cause more problems than it will solve.
My system does in fact successfully hibernate *sometimes*. It's rather time consuming trying to nail down when it will and when it won't so I don't have a ton of info yet in that regard yet but it does seem to be somehow related to the amount of memory in use at the moment. After a reboot and letting the system settle for a few minutes, I'm currently at 100% getting it to hibernate at that point. Open up a bunch of Chrome tabs, a bunch of IE tabs, some MS Office windows, etc. and it's almost at 100% fail rate when trying to hibernate. For a while, the problem seemed linked to only when I had some sort of browser open but I've been able to disprove that.
I thought I had fixed it for a while as, whether through direct cause or dumb luck, a modification I made to the registry drastically reduced the number of times the system would fail to hibernate. I can't find the pages that lead me to this idea at the moment but I added the IRPStackSize registry key to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters. This was apparently an issue that was prevalent in earlier iterations of Windows. The current value I have this set at is 40 (decimal) vs. the default of 15.
I'm hoping that this may spark an idea with those of you who have been trying to help with this issue. I'm currently grasping at straws and while this machine has barely been reprieved from being thrown out a window many times in the past, its luck may be running out. I'm continuing to work towards finding an answer but I just don't have the time to dedicate to it that it is looking like it will take. As such, I openly welcome any and all suggestions and will try to provide any further information that anyone wants. If nothing else, I'll update when/if I can make any progress on this.
