When i powered my MacBook Pro i received an error msg:
panic(cpu 0 caller 0xffffff8026a59241): "Unable to find driver for this platform: \"ACPI".\n"@SourceChache/xnu/xnu-2050.20.9/lokit/Kernel/IOPlatformExport.cpp:15 48
it lists bunch of hex numbers and Kernel Version: 12.2.1 etc....
How do i fix this so that i can use my macbook pro.
THanks for your cooperation.
Can you boot at all? If not, can you boot into "Safe" mode?

If you can get booted via "Safe" mode, can you post the full panic report?
Kernel Panic reports: Finder -> Go -> Go to Folder -> /Library/Logs/DiagnosticReports

The panic report should have "panic" in the file name.
If you cannot boot normal, and cannot boot into "Safe" mode, can you boot the "Recovery" partition?
Boot holding Command-R, then run Disk Utility -> Repair
Thanks for your quick response. I tried rebooting in safe mode but still received the same panic error. So I rebooted the machine in Recovery partition and ran Disk Utility - Repair on Macintosh HD partition that's where i have most of my files. It finished repairing successfully. I also tried the same on Disk 1 which is the Mac OS X Base System. But i could only verify disk as repair disk was grayed out. Should I reboot the system again?
Thanks

i also ran CRC checksum and completed with this msg CRC32 $1AC68BFC
You might want to re-install Mountain Lion over top of the existing install.
While the recovery partition is a striped down OS X, it is still running the operating system, just fewer drivers. That tends to imply that your hardware might be OK, and makes me think maybe the operating system has become corrupt.
Re-installing over top of the existing operating system will re-write new good files over any that maybe corrupt.
Of course the operating system modules should not become corrupt, but it does happen. A failing disk could cause this. Or marginal RAM. Both of which may not be bothering the recovery mode, so hardware failing is still a possibility.
You may want to make a Genius Bar appointment at an Apple store and have them perform a free evaluation (repairs you authorize would cost)
How do I fix the panic (cpu 0 call error...
