Re: New Debian sparc64 test kernel for stack corruption issue
Hi,
regarding T2000 Niagara T1 I did some tests using kernels from debian
snapshots. E.g.
https://snapshot.debian.org/archive/debian-ports/20250511T134440Z/pool-sparc64/main/l/linux/
I found that 6.13, 6.14, 6.15 were available and I tried most of them.
I was prearing a report file with various boots attempt.
Unfortunately doing lots of reboots, I ended up rebooting my running
workstation and not the SPARC server loosing everything. Ah! I was not
"connected" and xterms are look alike.

Take in consideration that on this sytem my sweet spot for kernel is:
6.12.38+deb13-sparc64-smp
Would you be able to bisect this?
The boot breakage appears to be with 6.15. I am unsure of the various
versions.
6.14 kernels do boot, although during usage I got VM issues (e.g. using
aptitude while running it)
Luckily I have the downloaded files so I coiuld reconstruct.

I don't know if there are later 6.14 kernels I can try or earlier 6.15,
but I would say that the issue is there.
Could be kernel code, change in configuration...
