Wireless card causing stop 0x9f (t60p w/Vista 64)

[Stucco]

I did a search and found a thread on several with this problem using XP but nothing relating to Vista or 64.

I have a T60p widescreen (8744-C9U). I recently upgraded ram to 4gb and to take advantage of it I upgraded the OS to Vista 64 bit. I have some problems with the wireless though.

If I change the power state at all, including sleep, hibernate or even just unplug from the wall, the wireless network will no longer be available. It will still appear as connected in the systray, but won't respond when hovering or going to "connect to". After about 5 minutes the system will BSOD with a 0x9f stop code DRIVER_POWER_STATE_FAILURE. There is no way to avoid this. If I try to shut it down or restart it, it will hang in the process until the BSOD. I end up holding the power button down each time.

Things I have done.

1) Install latest Thinkpad power manager (v2.50) and acpi power management (v1.53)
2) Update BIOS to latest (v1.15)
3) Update wireless card software/driver to latest (ThinkPad 802.11a/b/g/n, 802.11b/g/n Wireless LAN Mini PCI Express Adapter v7.6.1.237)
4) Turn off "Allow the computer to turn off this device to save power"
5) Uninstall all thinkpad power management software
6) Uninstall wireless software (leaving driver)
7) Uninstall wireless driver
Install alternate wireless software/driver (Intel PRO/Wireless 2200bg, 2915abg, 3945bg, 3945abg, 4965ag, 4965agn Mini PCI adapter v12.04.0000)
9) Turn off "Allow the computer to turn off this device to save power" again (guess it got turned back on when I changed drivers)
10) Uninstall wireless software (leaving driver)

Support pretty much said they don't support vista 64 on this machine. They know about the problem and there is not a solution.

I'm just about out of ideas here. Has anyone solved this?

P.S. I originally had this problem on XP 32 bit as well but a simple upgrade of the wireless driver solved it then.

Thank you for any input!!!

Just to follow up...no solution found. Downgraded to Vista 32 bit. Problem is gone.

I did not sse the first post. So, wireless card model / driver / power management are the likely culprits in Vista 64-bit. I have Vista Business 64-bit on my T61p and an Intel 3945 a/b/g card with all power managers (3) turned off (max performance). No problems of any kind. .. JDH
