Hi guys, After having tried various distros as mentioned and after having tried SLC and MLC PCI-E devices as well as SSD disks I think I actually found the issue.
Previously I had a bunch of SATA disks connected to my SAS controller as well as a bunch of SAS disks... now that I removed the SATA disks and only have SAS disks left I have not been able to reproduce the issue (regardless the fact I didn't even use the SAS controller for some tests that crashes). Very weird and what a waste of a few hundred hours of reinstalling/testing, swapping cables, switches, memory, messing with bios settings and what have we. I now have two stable pools which each write a reasonable ~430 MB/sec with sync=always on without crashing. Lesson - stay far away from SATA disks on LSI 9207-4i4e Thanks for all the feedback.

If you can, stick with r151010 (our latest stable) and get a system dump from this box. It's possible too, as Narayan points out, checking for HW errors is helpful. Also, I may ask you to reproduce this bug with kernel memory debugging enabled. If something is using freed memory, that'd be nice to know. And finally, are you using 3rd-party binary drivers? Or the native ones in your distro?
