System instability since 2.6 Beta
 
This could be a coincidence but I've noticed that after unplugging from one DisplayLink device or plugging into another, after a few system sleeps/resumes, suddenly the user CPU jumps to 99-100% (although for some reason I can't identify the process that is causing this). The system chugs to the point that a forced restart is needed

Anyone else seeing this king of thing?:confused:

I've noticed the same behavior with the 2.5.0 drivers on EC 10.11.5 the last few days...

I can't tell what's causing it because at that time the CPU usage is so extreme I can't open Activity Monitor anymore. And guess what, I only see this behavior when plugged in a DL-device. So I installed the 2.6 beta this morning to see if there's a difference. But what keeps me wondering is why I've had an "OK"-ish experience with 2.5.0 for months and the last few days CPU usage goes up to 100%?

Perhaps something changed in OSX then with a latest update.. I'm glad I'm not the only one experiencing this.

Like you, I can't open Activity Monitor or it opens but then can't refresh itself to get a process list. I've managed to open terminal and run top but that doesn't show any numbered processes misbehaving - just 0% idle CPU - then terminal stops being able to accept text input

I've had at least three very severe slowdowns in the last 10 days. Nothing usable really, had to leave the Mac alone for 3-5 minutes before it became usable again.
In two cases when using Parallels, in another case just browsing with Safari. No external screens connected.
Don't have a theory yet, the CPU did not seem to be the problem.

Will investigate further if it happens again. Thing is, I don't like to open Parallels at all but if it triggers the problem I'll have to.

I've just uninstalled the latest drivers - I just got a total slowdown where I had to reboot (cmd + ctrl + del) after finder bogged down viewing a PDF and I hadn't even plugged into the displaylink device. I can't say for certain if the displaylink drivers are causing this but I've never had this happen before installing the latest drivers - usually my mac is rock steady.
