System: NetBSD nelly.aprisoft.de 8.99.37 NetBSD 8.99.37 (NELLY) #27: Tue Apr 23 15:22:06 CEST 2019 martin%seven-days-to-the-wolves.aprisoft.de@localhost:/work/src/sys/arch/sparc64/compile/NELLY sparc
Architecture: sparc
Machine: sparc
>Description:

This happend on a sparc64 machine (running a 64 bit sparc64 kernel) with sparc
(32bit) userland (but I guess that is irrelevant), while extracting sets
via NFS to a local raid (on sd0/sd1).
