Nope, because suspend works but resume not. I will send a dmesg later, maybe someone is interested. A user at bsdforen.de told me, that is because of the optimus (you can't switch off the discrete GPU in the BIOS) in the machine (I don't know whether this is true or not). But it is not important because even I had in the past another operating system, I used it not really. > Why do you have 32G of RAM?

I bought the machine (a ThinkPad W541 with optical drive) as offered (the only ThinkPad with optical drive at this time) at the European u:book project, where you can buy hardware (twice a year) with round 20 % discount. At the time I bought it, I hadn't decided whether I stay (I came from Mac OS X) with Linux (because of the hardware support) or FreeBSD. After playing around, I remembered, that I saw round 1997 (or maybe it was a littlebit later - can't remember) the OpenBSD website (cool time with ISDN) and I gave it a try. What should I say, it simple worked out of the box and, does what I want / need (thanks to all developers). So, the machine is already there - now it will be used with OpenBSD. > Do you expect chain-reaction core dumps, where one application hits an > uncaught exception and dumps core and then its parent or some other > application that is communicating with it bombs and dumps core, too? ;-) > In other words, do you expect to ever have all 32G filled with stuff > that all at once dies and dumps core? Nope, but as I wrote, it is already there.
