next in thread | raw e-mail | index | archive | help
I posted this to -STABLE on Monday, since then I've come to understand
that -STABLE doesn't really include 5.0 (even though it's been released).
That, combined with the fact that I received no answer, has propted me
to post this to -CURRENT. Following is my original post:
<original post>
We're trying out 5.0-RELEASE on a test machine, and all is working well (so far)
except for the continual "calcru: negative time ..." messages.
I found information about this in the FAQ, but 5.0 doesn't seem to have a
kern.timecounter.method oid.
I also found information in the 5.0DP1 errata that pointed me to the -CURRENT
mailing list, but a search of that list produced very little information, and
the only thing to try (setting kern.timecounter.hardware=TSC) didn't change
anything.
Is there any more information on this? Is the last paragraph in the FAQ (that
my interrupts are too hosed) applicable? Any pointers/help is appreciated.
</original post>
Since I posted this, I've gathered a little additional information:
kern.timecounter.hardware is still set to TSC via sysctl.conf. It appears as
though this has changed behaviour. We aren't seeing the calcru messages any
more _except_ during boot, where they intermingle with the boot messages.
Does this mean that the calcru problems are occurring during boot, until the
sysctl is changed, and then they stop? Is this a reliable solution?
