Dear Maintainer,
lscpu crashes sig Floating Point Exception with some valid kernel
configurations. In particular, I have enables SMP and SMT scheduling but not
multicore since my CPU-s have only single core with HT.
While lscpu works with official kernel package, it fails to work now. It gets a
traps: lscpu[2379] trap divide error ip:4022bd sp:7fff4f976240 error:0 in
lscpu[400000+7000]
