I still have boot problems with this latest image. See [1] for my old

Not with this new (2025-12-06) version, but already since some versions
before, it became worse. In that I don't see any kernel messages after
the boot loader jumped to it, neither on VGA nor on serial console.
I know that this image worked for me on various machines:

Maybe you want to give it a try?
(A C3750 should work with it)
You should ask Helge Deller for advise as he is the expert for Linux on PA-RISC
and also the upstream maintainer of the PA-RISC Linux kernel code.
I haven't come around to build installation media myself as mentioned in
the thread [1].
Building your own installation media is a bit involved, here is an outdated guide for it:
https://wiki.debian.org/PortsDocs/CreateDebianInstallerImages
I'm not 100% sure what the best approach for building debian-installer with your own
custom kernel is. But I guess you could just swap the kernel image in the installer
images tarball with your own one and maybe unpack the debian-installer initrd.gz and
replace the modules directory in /lib/modules/.
But now I want to tackle that problem again (no kernel messages) in
order to finally have Linux running on my C3750 art some point in time.
I want to boot my test kernels over the network.
My questions are:
- which kernel version and config to use? I've tried latest Linus
version and 'generic-64bit_defconfig', but this gives compilation errors.
Yes, that should be able to boot.
(Note: The 64-bit debian 6.17 kernel has an issue right now, where it doesn't boot for me though).
What errors are you seeing? The vanilla kernel should build fine.
You need to build with "make ARCH=parisc64" when building a 64-bit kernel.
Make sure to have 64-bit hppa cross compiler installed.
If not, please let me know the errors you see.
Here is a quick guide on how to cross-build a Linux kernel for SPARC, the same applies
to PA-RISC, just download the corresponding toolchain for hppa instead of sparc64:
https://lists.debian.org/debian-sparc/2025/10/msg00103.html
- how would I build a bootable LIF file after I'm able to compile a
kernel? In the first step without userland, just to see the kernel messages.
"make ARCH=parisc64 palo".
Then you should be able to remotely boot the kernel via TFTP.
