[OpenIndiana-discuss] Sluggish Intel GFX recently

[Michal Nowak]

Hi.

Since November (illumos 85280f08e3 at least) the desktop gets sluggish 
once a day, especially Firefox 60 is redrawing only when mouse is moving 
over the page, scrolling in the terminal gets noticeably slow. Usually 
it happens 8-12 hours after boot, even when the laptop is not being 
used. Only restart helps.

I run Lenovo X220 (Sandy Bridge GFX) and always the latest illumos & DRM 
code.

Does anyone with recent illumos and Intel DRM experience the same?

When it happens I have following in Xorg.log:

(EE) intel(0): Failed to submit batch buffer, expect rendering 
corruption: Device busy.

And this in /var/adm/messages:
