The same as yours: VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06) in a I5-6500 CPU. > For whatever it's worth, I do *not* see any problems like this. Not > even close.

For the last 5 years this have been a constant pain, one problem after problem. When a problem got fixed by a new kernel a new problem appeared, for every single kernel version I tested. It even affected my ability to get the work done: yesterday I had 3 complete system freezes in less than an hour. But I use KDE, I use 3D acceleration, and I use programs who uses 3D acceleration so I constantly hit these kind of bugs. One of the less buggy kernels for me in the one in Debian Buster (4.19.0-8-amd64). Hangs are not so frequent with this kernel but the text consoles are corrupted: https://bugs.freedesktop.org/show_bug.cgi?id=107951 This capture is from my own computer: https://bugs.freedesktop.org/attachment.cgi?id=143903 The problem was solved in later kernels but the fix never reached Debian Buster. > The web page you linked also talks about "transition to idle", which > I'm guessing is related to CPU power management...? I'm using a desktop, so power saving is not a problem. Of course one of the multiple tests I made was disable GPU power saving, limit the C states...all the proposed workarounds that works for some users but none of them worked for me. I will try kernel 5.5 when available in unstable and if I still get hangs, I will try a different graphics card. Thank you.
