I think this is more likely a hardware issue. We haven't seen any machines crashing that
early. Please make sure the RAM modules in this machine are working properly.

I don't think so... I think it is a Kernel issue, since with kernel
5.9.0-2-sparc64-smp #1 SMP Debian 5.9.6-1 (2020-11-08) sparc64 GNU/Linux

the machine is performing fine with network, disk and compiler usage on all 32 CPUs.

Then you need to bisect the kernel as I don't have any means to reproduce the issue.

I have a T1000 with which I could try to reproduce Riccardo's issues.
Hardware wise they should be pretty similar. As the T1000 doesn't have a
CDROM, I'll try to netboot a few newer kernels and report my findings.
Will take me until next week though, as the machine is in (cold) storage

Aren't there some build servers using UltraSPARC T2 or T2+? Do they run
with the latest kernels?
