Hi,

I sometimes, but not very often, see that 3 kernel threads (swapper,
pagedaemon and aiodoned) show incorrect cputime just after boot :

njoly@lanfeust [~]> top
  PID USERNAME PRI NICE   SIZE   RES STATE      TIME   WCPU    CPU COMMAND
    0 root     -18    0     0K  155M schedu/0    ???  0.00%  0.00% [swapper]
   12 root     -18    0     0K  155M pgdaem/0    ???  0.00%  0.00% [pagedaemon]
   14 root     -18    0     0K  155M aiodon/0    ???  0.00%  0.00% [aiodoned]

njoly@lanfeust [~]> sysstat ps
USER      PID %CPU %MEM    VSZ   RSS TT  STAT STARTED       TIME COMMAND
root        0  0.0  0.0      0 158760 ??  DLs   2:21PM  71582788: (swapper)
root       12  0.0  0.0      0 158760 ??  DL    2:21PM  71582788: (pagedaemon)
root       14  0.0  0.0      0 158760 ??  DL    2:21PM  71582788: (aiodoned)

I already experienced this behaviour on 2 of our amd64 machines (2CPUs
and 4CPUs) running -current (2.0F 20040602).

njoly@lanfeust [~]> uname -a
NetBSD lanfeust.sis.pasteur.fr 2.0F NetBSD 2.0F (LANFEUST) #2: Wed Jun  2 14:27:13 CEST 2004  njoly@lanfeust.sis.pasteur.fr:/local/src/NetBSD/obj/amd64/sys/arch/amd64/compile/LANFEUST amd64

Is this a known problem ?

Thanks in advance,
Regards.
