still waiting for root device

[Kevin Jieu]

Just installed Lion on my Thinkpad (with Core 2 Duo CPU), installed a few kexts for my specific hardware, but booting hanged. Here's the last few lines of the boot output with -v:

 

ThinkpadUltraNav loaded
ThinkpadUltraNav: mouse info 0.0.102
No interval found for . Using 8000000
VoodooPS2TrackPad: Synaptics TouchPad v6.2
[iOBluetoothHCIController:setConfigState] calling registerService
rooting via boot-uuid from /chosen:82BA[...]
Waiting on <dict ID="0"><key>IOProviderClass</key><string ID="1">IOResources</string><key>IOResourceMatch</key></string ID="2">boot-uuid-media</string></dict>

 

after a dozen seconds, I got:

Still waiting for root device
Still waiting for root device
...

 

I modified com.apple.Boot.plist, setting bootflag to use bsd style device id rather than uuid, but I'm still getting the same message...

 

Help please,
