The issues seems to be limited to the Vertex 2. I just spent the afternoon clean installing (after a secure erase) Windows 7 on each of my SSDs and testing (to rule out my laptop being the culprit):
1. OCZ SATA II 64GB (original, SLC version of the drive). No issues with sleep or hibernate.
2. Intel X25-M 80GB (G1). No issues with sleep or hibernate.
3. OCZ Vertex 2 100GB (firmware: 1.10). Hibernate is okay, resuming from sleep causes a BSOD (sometimes immediately, sometimes after a few seconds) or just shuts down instead of resuming (not a regular shut down - one that causes Windows Error Recovery to pop up upon restart).
I have requested that OCZ look into this. Is there any way that I can request that Intel do the same?
