I do have freezes and crashes with the 5.4 kernel and have to use 4.19 consequently. But I don't know what causes it. How did you determine that it's the i915 driver in your case?
Sad for you, but I am kind of happy that I am not alone :) Maybe you add your experience to my bug report https://github.com/QubesOS/qubes-issues/issues/6397 as well? Sometimes I need a vanilla debian (life system on usb) to uefi-debug / emergencybackup. And even that one hangs from time to time, by spitting out a last word [drm:intel_cpu_fifo_underrun_irq_handler [i915]] ERROR CPU pipe A FIFO underrun Since the std debian is very stable and much less complex than xen + qubes, I take that as a hint (badly enough, when qubes freezes happen, qubes dies faster than kernel logs are written, so I have no other starting point anyways). For these reasons, my suspicion was early on the i915 driver. Also, i915 seems known problematic from 5.x kernels onwards any kind of other linuxes (google it). cheers, Bernhard P.S: my chipset is an intel 620 [8086:5917] rev 07. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
