Hi, On one virtual machine (qemu on cygwin) running RELENG_8 (csupped around 12.Sep.11) -- I noticed: $ ps aux USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND root 0 nan 0.1 0 64 ??

I then rebuilt world and kernel with GENERIC and removed all the changes I had made in /etc/make.conf -- but this also didnt help. I run qemu without the -cpu flag and dmesg shows: CPU: QEMU Virtual CPU version 0.15.0 (2216.03-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0x633 Family = 6 Model = 3 Stepping = 3 Features=0x781abf9<FPU,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,PGE,CMOV,PAT,MMX,FXSR,SSE,SSE2> Features2=0x80800001<SSE3,POPCNT,HV> Any pointers how I can get my WCPU values back -- its a little difficult if I cannot sort by WCPU in top. Thanks, Gautam
