[qubes-users] Kernel 5.15.XXX

Hi,

since a dom0-update at the beginning of July 2023 I get a black screen after the bootloader. I can only boot Qubes if I select Xen 4.14.5 with Linux kernel 5.15.103 in the bootloader instead of the default (Xen 4.14.5 with Linux kernel 6.1.35). See here: Black screen after start since dom0 update (now kernel 6.1.35) · Issue #8354 · QubesOS/qubes-issues · GitHub

Questions:

1) Will the kernel 5.15.103 be automatically deleted during the next dom0-update or do I not need to worry?
2) Is it possible to set the kernel 5.15.103 as default?

Kind regards,
Michael Singer
