New test kernel available - please verify

[John Paul Adrian Glaubitz]

Hi,

I just uploaded a 6.16.3 Debian kernel package with:

- all patches by Michael Karcher to fix copy_{to,from}_user
- the patch by Anthony Yznaga to fix HugeTLB support on sun4u
- support for transparent huge pages disabled

Packages are available here: https://people.debian.org/~glaubitz/sparc64/

Please test and report back!

Adrian

Never mind, it's broken. Most likely due to the binutils version used.

Will have to rebuild with binutils 2.43.

New kernel is building, old packages have been deleted to keep users from
testing kernel packages known to be broken.

OK, even building with binutils 2.43 doesn't help. We've got to stick with
6.12.x for now, it seems until I have found out what broke in Debian's
6.16.x kernel.

a bit old news now, but yesterday I tested this kernel (I saw there is a 
new one... will test that too) and it installs and boots fine for me on 
a Fire T2000
It works with a "warm reboot" too.

I was able to compile on all 32 core, use git, do some apt-get upgrades. 
I surely stressed CPU, Disk and Ethernet decently. No evident issues found.
Of course, not testing of multi-day long running stability.
