Shutdown/Restart Hang

=P

If it weren't for this, the DVD problem, and wifi, everything would be perfect. None of it is really a big deal...

I'm already using his latest fakesmc.

It's due to some USBEHCI thing. It said that restart/shutdown was still waiting on USBEHCI or something like that.

Ok. If I boot in 64-bit mode (-x64 -v), I won't get Qe/CI, which will not turn my screen off when shutting down/restarting, so I can see any sort of messages.

Here's what it said:

PowerOff: still waiting on AppleUSBUHCI

Any ideas? I may try repatching the DSDT and doing the CMOS fix to see if this will help.

same problem for me

i have in my EXTRA folder these kext :
PlatformUUID.kext
OpenHaltRestard.kext
IOAHCIBlockStorageInjector.kext
fakesmc.kext
AD1988b.fix.kext

i have to wait for a minute every restart or shutdown

Motherboard : P5E

hope someone have solution to fix it

Try installing both ...SleepEnabler + NullCPUPowerManagement … both are needed for the system to sleep and wake.

@BeSweeetWhen I shutdown/restart, it just hangs there for a minute and then boots. I think this is related to a USBEHCI problem. I remember seeing once (don't remember where I saw it though) that it said that reboot was waiting on something USB related.

like alway netkas has a fix a new fakesmc
it just might work
goto his website good luck

SleepEnabler should fix Sleep

OpenHaltRestart should fix Restart & Shutdown

DSDT should fix various compability issues

NullCPUPowerManagement disables IntelCPUPowerManagement

so make sure all four are properly installed and running

I tested all these kext but no quick restart
i patched the usb devices in dsdt to got sleep working and it work without sleepenabler,
but no solution for the long time restart

Exact same prob here too , other than that its running great quite snappy too

This is an issue that's plaguing me too ... (asus p6t deluxe v2) I'd like to just confirm that mine is the same reason for it..

how would I go about checking my logs that are created at the time of shutdown if there are any?

Is there a dsdt patch fix to get the shutdown/reboot work without the OpenHaltRestard.kext ?
maybe it can solve the problem ?

i have already patched usb devices in my dsdt, so i don't think the problem is the AppleUSBUHCI on my install

I get the same error. honestly i assumed it was a crash until i read your post, I disabled the graphics detection and, for once, waited and there was the message. It happens 90% of the times, I still have not figured out what do I do different on the other 10%. I already tried to enable the USBFix from chameleon with no success.

I am running 10.6.1 with only fakesmc and voodooHDA. No DSDT.aml. The system is much more stable without it. Absolutely rock solid actually, this is the only glitch.

I have an ASRock P45XE with ICH10.

Anybody figured what is wrong with it or even better a fix?

EDIT : I also forgot to mention that I also tried Openhaltrestart.kext with no changes

I dont have this problem on my ASUS P5K-E Wi-Fi (had it in leopard), i have:
SleepEnabler.kext
fakesmc.kext
OpenHaltRestart.kext
AD1988bFix.kext
and dsdt.aml patched as written in the P5K-E WI-FI thread..and my Jmicron controller disabled.
Actually Snow Leopard shutdowns and restarts are amazing fast way faster then Windows 7.

However i have the same issue on the MSI P43 Neo-f and also sleep and shutdown problems :S

Any of you has arrived to some conclusion regarding this issue?

In my system that happens when I have Legacy USB support turned on in the BIOS, though it just sits there for 1-2 mins before eventually restarting. If I disable that I get perfect restart and shutdown (Intel ICH10 USB).

i tried to turn on "BIOS setup only" but that did not make a difference. it is rather silly, but i can't put it in disabled because i do not have a PS2 keyboard to turn it back on.

Thank you for the suggestion. The weird thing is that it is not always. I already disconnected all the USB devices other than the keyboard and the mouse with no difference.

Cheers for the suggestion though

Good point! You would be locked out of your own BIOS...
You could try using Chameleon's USB reset options, they didnt work as expected for me though (with a NVIDIA board, EHCI reset worked but UHCI didnt...).
