MacPro3,1/10.8.2 intermittent freezes multiple times a day

Question

For the last two weeks my MacPro 3,1 has been experiencing three to five intermittent freezes per day. The last couple of days I have experienced nearly one an hour.
I have not been able to peg it to any specific system update, application or hardware issue. There are no kernel panics in relation to this issue. This MacPro originally started with a fresh install of 10.6.x, and has been a stable system through all OS updates, up to and including 10.8.2.
The freezes have occurred with various programs running: (only) Finder, various elements of CS6, iTunes, Mail, Terminal, Activity Monitor, etc. iTunes will continue to play music. Activity Monitor will update statistics in graphs for a limited time, while the process monitor responds for a longer time. After a freeze I have mouse control and can click between on-screen windows and applications. The menu is non-responsive. I will occasionally get the beach ball of death. The only recovery is a hard power down and reboot.
In attempting to diagnose the problem, I have experienced similar freezes with a fresh install of 10.8.x with no 3rd-party software on a temporary partition. This led me to believe I had a hardware problem. I pulled and reseated all RAM, the four hard drives and SSD, the video cards. I ran SoftRAID's non-destructive verify on all four of the Samsung HDs, which then predicted a potential problem based on one of the drive's SMART data. I then backed up the data located on the RAID and did a three-pass certify-level test on the suspect HD with SoftRAID, which cleared the drive of errors.
Any ideas are greatly welcome. I have included the system information and one system log from this evening while attempting to copy files from an external drive to the RAID.
Thanks much!
Tom

Answer 1

Ah, the "20 Questions" - mention m4 and would have said to check you have the latest firmware. Common enough that after way too long lengthy threads to get to the bottom.
Even Zero all does not rule out bad sectors all the time, but it does insure the headers are good when you format a drive or setup an array. I thought the latest SoftRAID 4.x scanned in the background during idle time AND it reports disk I/O retries (bad is a bad work, 'weak sectors' is probably more accurate: is 5 retries bad or is 10?). Is not a 100% black/white issue.
Firmware is hardware and heck, OWCs own SSD controller is throwing out a bunch of corruption issues too.
iTunes use to be good at detecting weak/bad RAM. AHT isn't. Memtest may not (especially with ECC) and DIMMs also have firmware, SPD code and variations.
SSDs though with the constant improvements and change have been popular issue. In May-June a bug in the latest SandForce controller firmware that took a long while to get to the bottom.
Odd that Crucial doesn't say more or the comments section on Newegg and Amazon don't have more?
