Dear qubes community, I use qubes since its version 3, with many up's
and downs (more up's, happily). Since its version 4 it worked quite
stable, but this changed since some months. I am obliged to hard-reboot
my machine 5-10 times per day, versus a scheduled reboot every two-three
weeks before.
- Somehow the 5.4.x kernels (for xen) are instable on my machine. They
run smoothly my debian appvm's. No clue if the kernel its crashes, but
after 2-15 min the systems becomes unusable: the screen "hangs" and no
other way out than hard reboot. I have a rather std i7, I mention. HCL
attached. My problems:
- The last upgrade removed my last 4.9 xen kernel which would work fine
(how can I get that one back??) so I switched to 5.10 directly. The last
one braught by update won't work: under 5.10.11 kernel, NO WAY to boot a
debian-vm. Journalctl says:

- when running zoom with 5.10.5 xen kernel inside a dedicated zoom-vm
(debian-10) inside firefox (no custom app). The system "hangs" screen
hangs, sound loops over last second, and that's it. I do not see any
special before the problem occurs (see down) but there is something
strange while boot. It is displayed for each CPU separately.
