I have identical symptoms after my recent upgrade, so I thought that I add my observations.
I bought Lenovo T520 (90% intel based devices) and was migrating everything from old R61. [ snip a list of problems ]
Did you try upgrading the BIOS first? With new computers I always find necessary to upgrade the bios, since bugs are found after they are on the market, and laptops sitting in warehouses wont be upgraded.
After that try running memtest86 for a while… it might as well be faulty RAM.
I was running memtest for 10h, no errors found.
But I found out that when mouse starts jumping reloading the iwlagn module helps. Of course networkmanager restarts my connections, but it keeps Firefox running and I no longer see Firefox crashes.
I'm now running without iwlagn module and on external Linksys USB wifi card. System seems stable.
As for BIOS, in fact it is pretty old (1.31 vs newest 1.34). I'll upgrade it later and post results.
Thanks for the hints.

I have had the mouse jumping problem myself on various laptops and in every case it was caused by not having installed xf86-input-synaptics. Just thought it was worth a mention. Clive -- Infinity: A concept for those who cannot comprehend the big picture. () Arch Linux - For movers and shakers. ()
