Using the same kernel config and adding a --ramdisk in palo.conf (using
install/initrd.gz from 2025-12-06 CD) lets the kernel crash early, like
the other kernels I've tried. No further output after the palo loading
messages.
So it crashes right at the start of the kernel, unlike without an initrd
where the kernel boot messages appear normally and it crashes because it
has no rootfs and init program.
Maybe debugging with earlyprintk can help?
Try passing "earlyprintk=serial,ttyS0,115200" to the kernel command line.
See: https://wiki.gentoo.org/wiki/Kernel/Command-line_parameters
You mentioned, that "your" kernel does not crash, and that you run
on serial console.
Can you please capture the full output and post it here?
Then maybe I'm able to see what the difference between your machine
and all others is.
Do you maybe have some PCI cards, e.g. graphic cards or others added ?
You mentioned that the standard kernel failed to detect your CDROM drive.
In most (somewhat newer) HP machines the CDROM drive was ATA connected
to on-board controllers.
Then I tried extracting the initrd.gz file system (replacing lib/modules
with my kernel's version) and mounting it over NFS. I modifed the kernel
config to compile in NFS client support and not get it from modules.
Would be good to figure out what the actual problem is so we can fix the
issue in Debian or in the upstream kernel.
Yes, for that the log would be good.
This worked so far that I could start the installer (it would find the
CD in the CD drive as installation media), but it complains that the
installer components (I believe kernel modules) are for a different
kernel than the booted version.
Yes, that's expected.
