Problem with a LSILogic SAS/SATA adapter on 8.2-STABLE/ZFSv28

Hello list,
I have a problem with my 8.2-STABLE/ZFSv28 server. I am currently
upgrading my disks from 1.5TB Seagate drives to 2TB Seagate drives, and
therefore replacing devices within ZFS. (I have activated deduplication
on a few file systems, for the record)
I think this is more related to a hardware problem (flaky memory ? flaky
controller/driver maybe ?), but I would appreciate any input.
I experienced several kernel panics, all of which seem to point at mpt0
mis-handling interrupts :
www.darkbsd.org/~darksoul/kernel-panic-mpt1.txt (no target cmd ptrs)
www.darkbsd.org/~darksoul/kernel-panic-mpt2.txt (mpt_intr index == ...)
www.darkbsd.org/~darksoul/kernel-panic-mpt3.txt (NMI in kernel mode)
www.darkbsd.org/~darksoul/kernel-panic-mpt4.txt (LAN CONTEXT REPLY)
www.darkbsd.org/~darksoul/kernel-panic-mpt5.txt (LAN CONTEXT REPLY)
www.darkbsd.org/~darksoul/kernel-panic-mpt6.txt (LAN CONTEXT REPLY)
www.darkbsd.org/~darksoul/kernel-panic-mpt7.txt (LAN CONTEXT REPLY)
I would appeciate any pointers to what on earth "LAN CONTEXT REPLY"
means for an LSI controller (using driver mpt(4)), as I have no idea,
and the source was not really helpful.
The error message about an NMI and RAM parity error is what is scaring
me the most here, and points me in the direction of flaky memory.
This is a personal machine, so I can add debug options and try stuff if
it can help figure out what is going on. Also, any critical data is
replicated, backed up and accounted for.
Thanks in advance for your time.
