Unfortunately not at all. To date, I even cannot reproduce locally, it 
reproduces exclusively in opensuse build service (and github CI as per 
Matthieu's report). I have a project in there with packages which fail 
more often than others:
  https://build.opensuse.org/project/monitor/home:jirislaby:softlockup
But it's all green ATM.

Builds of Go 1.24 and tests of rust 1.90 fail the most. The former even 
takes only ~ 8 minutes, so it's not that intensive build at all. So the 
reasons are unknown to me. At least, Go apparently uses threads for 
building (unlike gcc/clang with forks/processes). Dunno about rust.
