Turned out that this machine had a buggy BIOS and problems have disappeared after a BIOS upgrade. |
Reproducible: 100% Steps to reproduce: Attempt to install the Canna package from rawhide, or just run the /usr/sbin/useradd -c "Canna Service User" -r -s /sbin/nologin -u 39 -d /var/lib/canna canna command directly. Expected: user is added. Actual: After several seconds (strace shows a lot of YP traffic), I get an Oops: ------- Unable to handle kernel paging request at virtual address ffffffffffffffff printing rip: ffffffff80163ac6 PML4
