>Description:
Hello,
I own a Dell Latitude E4310 with a i5 560M and a gen5 Ironlake mobile iGPU.
I wasn't able to reproduce complete crash again (but still weird behaviours) as it seems a bit random, but still some visual problem and kernel logs appears so I'm going to detail everything.
First at boot without doing anything, on both RC5 and RC6 I got.
[ 4.664050] intelfb0: framebuffer at 0xe0010000, size 1366x768, depth 32, stride 5504
[ 6.194048] {drm:netbsd:intel_cpu_fifo_underrun_irq_handler+0x64} *ERROR* CPU pipe A FIFO underrun
Then with glxgears with both the integrated MesaLib (19) and the pkgsrc Mesalib (more recent 21.3) glxgears behave weirdly.
Please find the video in the following link.
https://www.swisstransfer.com/d/6e0ba072-2451-4008-97da-92a308c8d2ab
Sometimes in both RC5 and RC6 I got crashes but I was not able to reproduce again and did not keep the .core generated, so my bad.
I used the default CTWM WM as GUI.
Here are the dmesg after the weird glxgears

After these bugs the glxgears seem to work nicely though when restarted.
I also got crash with firefox on websites with videos (not youtube), but random websites with h264 and probably h265 videos.
I had enabled webgl for at least webgl1 (my gpu does not support webgl2). and it worked. But still crashes.
I removed core dump the past week and wasn't able to reproduce again for this report... so
Also crashes seemed more frequent on the more recent MesaLib.
But still the dmesg seem quite explicit.
However in my tests I think I had some
Here is the complete dmesg

Right now, I understand why webgl is disabled by default even if I am unsure it is was caused that on Firefox.
However I think sad this "non-fancy" hardware got problems with NetBSD.
The computer also does not get out of suspend properly, but I don't know for that if I'm doing something wrong.
But I only used the suspend fn button for that so I believe not getting out of suspend is a bug.
PS maybe Crocus could be a good add-on for MesaLib.
Cheers,
>How-To-Repeat:
An Ironlake mobile gpu.
NetBSD 10 RC5 or RC6 full installation with xdm enabled.
Run glxgears.
Try to have a desktop usage.
>Fix:
No idea
