Boot error : Sleepimage already in use /memory allocation error
I had a perfectly fine running Leopard 10.5.6. Only issue was with sleep (would not come back) and heating. Thinking it might be because of wrong graphics kext tried using Universal Installer 1.2. Did kext loading and Graphics card (Intel GMA 950 - laptop). It showed that Disable.kext, AppleDecrypt.kext and OpenHaltRestart.kext will be installed. Install was a success.
Upon booting again I get the following message
Sleepimage already in use
Loading Darwin x86
The above keeps flickering for sometime and then i get the following messge
Memory Allocation Error (0xf000f000, 0x2)
Please advise how to resolve the same.
