Sys-usb crash when printing

I don’t believe this is a duplicate of my previous post here:

This has a very clear cause, happens when sending print jobs to USB printer. Doesn’t happen every time. But has started happening much more regularly. I have many examples of the below if helpful to post more examples.

Did you try increasing amount of memory assigned to your sys-usb?
You can also try to use latest kernel version from current-testing repository for you qubes:

sudo qubes-dom0-update --enablerepo=qubes-dom0-current-testing kernel-latest-qubes-vm

I think I only increased the initial memory. Max was at 2GB, so increased to 4GB and will report back. Though I never saw memory use go high, I have seen CPU usage go high in sys-usb before a crash sometimes. (i have 2 VCPUS)

re: Kernel

I noticed I had it set to 6.6.25 for sys-usb, rather than default of 6.6.31. Changed that as well. Will report back.

4GB Max memory and default kernel of 6.6.31 did not help, still crashing regularly on print

You can try kernel-latest-qubes-vm from stable dom0 repository, the kernel there is 6.9.2.
Or maybe you can try the kernel installed in VM instead of kernel provided by dom0 if this issue is caused by the kernel provided by dom0:

6.9.2 kernel still getting regular crashing now (though at first it seemed to not be crashing, today i’m having to restart sys-usb and reconnect everything after most print jobs)

6.9.10 kernel
4GB RAM
Still having to restart sys-usb after almost every print job.

After a lot of testing, I’ve found that copying all my files to sys-usb and printing from there does not cause crashing. This is slightly more convenient than having to relaunch sys-usb and reconnect usb devices every time I print something.

Note: sys-usb is a disposable fedora-39

I had to install additional software in order to do my printing from it

Printing direct from sys-usb continues to be crash free. However it is real slow when printing multiple PDF. top shows it is gs that is using 100% cpu for a minute or two before printing begins (and continues slowly). I’m seeing what this person explains here: Why does printing a large number of copies take so long for CUPS to process? - Unix & Linux Stack Exchange

When I print from whonix I do not get the same delays, printing begins before gs kicks in and uses 70% cpu. In both cases I’m printing from evince.

The other thing I’m seeing in sys-usb that is regularly using 45% CPU is

/usr/libexec/packagekitd

I have not correlated either of these to crashes in sys-usb. So not sure if they might be causing the kernel panic error in my first post above.

Good news. Since installing libreoffice and system-config-printer into fedora-39 (the template for sys-usb) I have stopped getting crashes when printing from my whonix workstation. Seems likely the latter was what helped? Unless there was some other package update around the same time that fixed it. But happy to report I haven’t had a crash since then, after many many print jobs.

Note, i used
dnf history list
in fedora-39 to confirm what had been installed (just the 2 packages above). Other actions around that time were qubes-vm-update. I ran:
dnf history info 93
where 93 was the ID for the update that happened that same day and it returned:

Aside from kernel upgrades, cups-browsed and libppd are also notable and possibly related to this problem being fixed?

Well, the above didn’t last too long. I’m now getting a slow death of sys-usb when I print. USB devices freeze. qvm-ls shows status of sys-usb as “Dying” for a minute or two until it finally shuts down and all usb devices disconnect.
