Description Mark Johnston freebsd_committer freebsd_triage 2018-06-29 23:12:12 UTC 
When I start top(1), the CPU line looks like this:

CPU:  3.0% user,  1.3% nice,  1.3% system,  0.1% interrupt, -66.8% idle

After the first update the value seems to be correct, but then it's displayed with two decimal digits instead of one:

CPU:  2.1% user,  0.5% nice,  1.1% system,  0.1% interrupt, 96.38% idle

This is r335792.

Is an SMP or a UP system? I can't reproduce. Is this true for you with `-b` or only on the first iteration of an interactive display ?

Did you mean a different revision?

Hmm, after a reboot I can't reproduce it anymore.  I have no idea why.  This is on i386 FWIW.  I'll reopen if it happens again.

No.
