Vista - BSOD Vista64 Driver_Power_State_Failure

I'm going to make this brief, because the last time I had a BSOD in the middle of my post. Here's my situation, random BSODs. Diagnostics:

Can any guru tell me what may be going on? I've replaced drivers for firewire and for audio. Thanks.

Ok, now that the above is posted, I'll take a chance and try to give a little more detail. The machine is a new HP Pavillion A6750. It has an AMD CPU, with 8 gigs of RAM. The problem seemed to start after my old machine crashed (HD controller went bad) in the middle of a PCmover move. Afterwards I conducted a PCmover "undo," which consistently hung after about 90 completion. Perhaps some remnant of the aborted move is causing a problem? Seems strange, though, since PCmover doesn't move drivers, per se. I have already replaced the audio driver with the latest from realtek, and the deleted and had the system reconstruct drivers for the firewire HDs connected to the computer. I think I've pressed my luck here, so I'll save.

Info on external firewire drive: 750 gig, Maxtor One Touch; 500 gig, Seagate FreeAgent Pro.

Update: After disconnecting the Maxtor, but leaving the Seagate in place, it's now been several hours without a BSOD. The Maxtor was daisy-chained to he Seagate. I'll keep you posted tomorrow if this good behavior keeps up, or is just an anomaly.

Update: It's now been about 18 hours with no BSOD. Perhaps it was the drivers for the external Maxtor firewire drive. Anyone know if there are drivers that actually work with Vista64? Other thoughts?

It's now going on 24 hours since I disconnected the Maxtor firewire HD, and still no BSOD. Anyone have any idea what's wrong with Maxtor drivers on Vista64, and if there's a fix? -- assuming that I've actually found the problem. So far, this is an interesting conversation that I'm having with myself.

That's what happens when you price yourself out of the market by asking something very intelligent

Do you have SP1 applied? What's the timestamp on your sbp2port.sys driver?

Check this out:

You receive a Stop 0x9F error when you wake a Windows Vista-based computer that is connected to an IEEE 1394-based device

You might want to apply this hotfix and then test again:

Error message when you wake Windows Vista from sleep: "STOP: 0x000000B8"

My problem isn't related to coming out of hibernation. I've already read those threads and tried the hotfix. I do have SP1 and am up to date on all patches. My sbp2port.sys date stamp is 1/20/08. Thanks for your help. I'll try to act dumber the next time! :-)

The specific symptoms described by KB articles are frequently only a portion of what might happen due to a given root cause. Sure, that article talks about hibernation, but that might simply be the scenario in which MS encountered the problem - there may be others.

Since you seem to be able to repro easily, I'd suggest trying an even newer build of sbp2port.sys. KB seems to suggest that this one is the latest:

Stop error when you attach a Niveus Ice Vault Disc Changer to a Windows Vista SP1-based computer or to a Windows Server 2008-based computer: "STOP: 0x0000007E"

Thanks, I'll try the hotfix and report back.

Well, it's been about seven hours since the hotfix was applied and no BSOD with Maxtor Firewire external attached via diasy chain. Not sure I'm out of the woods yet, but this is encouraging.
