Shot in the dark in the unlikely event someone else has dealt with this strange problem.
Just bought a crucial m500 240gb ssd, installed into a sandy bridge system from a couple of years ago using an Asus p8p67 ws revolution mainboard and an i7-2600k. When I cold boot the system, I get a Kernel_Data_Inpage_Error. Something is happening as it tries to load system files. The system then reboots, and loads to desktop and seems 100% stable. On a restart, the error doesn't appear. Only when I completely shut down and power up.
Windows 8 installs fine, no hardware errors appear from any test I run, chkdsk, memory diagnostics, etc. I've tried everything I can think of. I've switched the sata ports on the drives, I've changed virtual memory settings, updated the motherboard to the current BIOS revision, erased partitions, did a slow format and reinstall, messed with voltages in case it's some sort of power issue on bootup. I'm getting no errors anywhere, no leads as to what it could be. There is no updated firmware for the m500.
Really don't feel like sending this drive back. The system seems 100% stable, aside from cold boot. I could live with that personally, but this is a build for a friend, and would rather not send him a machine with a glaring, if minor, problem like this.
