32-bit SPARCs are currently not supported in Debian.

We've received reports of two successful test runs on SPARC T1 in the mean time.

It's an installer CD as far as I know, but I haven't tested it myself.

There can always be hardware issues that are not visible with certain kernel
versions. You can only be sure if you run a memory test program.

Which indicates that the kernel can run stable on your machine. I'm currently
not sure what the problem is. There are some other unreleated issues that affect
Debian's kernel package only that I am currently examining. A patched upstream
kernel will most certainly work.
Please try booting the T2 ISO on this machine and see if that's stable.

The 6.16.3 test kernel contains the fix for M7/S7/M8 only. It's not expected
to work on other machines. Please just ignore it.
