Just changed computer at the office to a new HP Workstation z240 and have massive problems getting it stable.
Had problems already when installing Jessie with random hangs, but after many tries I managed to install. The freezes continued though, and after a while i pinned it down to that when "Multi-processor" is disable in bios everything works as intended.
But this is of course a far from optimal workaround since I really need all the power I can get from my shiny i7-6700.

At one occasion I happened to be in tty1 during a kernel crash, which at least gave me some crash info
But I'm very unsure what to make of it.
I have tried to run the latest kernel from jessie-backports (think it was 4., but with no success, so changed back to latest stable one again.

I have ruled out a hardware error, but have not tested it extensively. It's a completely new computer, and even though I did not run Windows on it for more than about 30 minutes (just booted the pre-installed windows, ran setup to update BIOS and some other firmwares from whitin windows) before formatting and installing Debian, all problems started as soon as Debian came in to the picture. Also have not tried other distros for the moment since its Debian I want to run, but maybe some live distro from USB could be runt to rule out hardware issues.
Anyone with an idea how to proceed to get this machine fully running?
