The last 2 or 3 kernel updates seem to have triggered a regression

the i915 (internal Intel GPU) driver. I get damaged screen updates,
very noticeable tearing on videos and occasional freezes in the DE
(Plasma under X11). A look at the journal shows:
Feb 19 16:33:16 Bree kernel: i915 0000:00:02.0: [drm] GPU HANG: ecode 7:1:cbd2d2d2, in
chrome [8728]
Feb 19 16:33:16 Bree kernel: GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
Feb 19 16:33:16 Bree kernel: The GPU crash dump is required to analyze GPU hangs, so
please always attach it.
Unfortunately I'd rebooted before looking at the journal, so
/sys/class/drm/card0/error is currently empty. I'll capture it next
time around, but it the meantime has anyone else seen this?
Don't have this HW. But a quick search suggests adding "nomodeset" to the
boot parameters.
