Hello, I just joined, and I was hoping someone might be able to help me with a problem I've been having. I recently purchased a refurbished Mid-2010 15" i7 Macbook Pro which I upgraded with 8 GB of RAM (OWC) and an OWC Mercury Extreme Pro SSD (240 GB; installed in main HDD bay). Following a fresh MacOSX installation on the SSD (no test prior to drive replacement), I found that I could not restore from hibernation (following battery calibration). The progress bar permanently freezes at the 1/4 or 1/2 mark. Subsequent tests using SmartSleep (manually set to Hibernate Only) indicated that this problem occurs any time the computer hibernates. Upon reboot following the freeze, there is a crash report (the same every time) part of which I've pasted below: I've reset the SMC, which had no effect. I've also tried closing any background processes and disabling any self-installed kernal extensions (MacFUSE and the like). Since I also had this problem before I installed these programs, I didn't think they were the real problem. I then thought it might be an issue with the SSD's firmware or a bug in MacOSX (as Windows hibernates fine). I've found a few reports of similar problems on newer Macbook Pros with replacement HDDs/SSDs. If anyone has any idea how to resolve this problem, please let me know. My current workaround is to disable hibernation altogether using SmartSleep (Sleep Only). Thanks!
