Hello, I wonder if some of you guys have the bad luck of an i915
graphics card and found some solutions. For me, no >= 5.4 xen kernel
works (freezes). So I still run it on 4.19
I first thought this to be an "evolution problem" since I use and update
Q4 since its beta state. So I tried a new install on a new disc, but
that fails even before finishing install, freezing as well
Even a plain "live debian" freezes from time to time with i915 errors,
which gives a clue where the problem comes from.
Is there maybe a way to tweak the installer? Thanks,
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?
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.
Wicked! That is very smart, thank you for the lesson! I am fighting
since 7 months with it without having had that simple & brilliant idea best, Bernhard
(that requires deleting kernel-latest-qubes-vm, if present). Then you
need to do an update-grub or something similar to build the downgraded
version in the respective initramfs ???
