Re: New Debian sparc64 test kernel for stack corruption issue
Hi Adrian,
sorry for the "delay"... had to kick some bugs in GNUstep application as
well as getting NetBSD/ppc on iBook up-to-date as well as kicking out
updates on NetBSD/sparc... which is now churning out binary packages
again. Not Linux, but still in the nice Big Endian domain!

Which bug is this? The stack corruption issue? If yes, then yes:

To me it appears different from the error log. Thus I opened a new Issue:
https://github.com/sparclinux/issues/issues/45
There I copied some of the information I have up to know and will post
further information I try while tackling down the issue.
If it is a duplicate, we can mark that, relate or merge issues.
I have posted instructions on how to cross-build and install your own kernel
not too long ago, see:
https://lists.debian.org/debian-sparc/2025/10/msg00103.html
I don't think it's particularly hard.
Shouldn't be hard. I'll make attempts and let you know. My first step is
to create a 6.14.11 kernel from kernel.org with config of debian 6.14
and hope it boots. That would prove latest 6.14.11 works and that I can
build a kernel, if that fails, back to 6.14.6 that I tested as debian
packages.
This would gives us some fixed points to work on, including being able
to build a bootable kernel.
Then build the first 6.15 series and see it fails or increase tag
version until it fails.
Then start narrowing down, hoping we can do some smartness beyond
bisecting brutally.
Riccardo
PS: I will document the steps myself on a blog entry!
