Hi All:
Before you throw this in the RTFMLA pile, I have. What I'm puzzeled by is
some other oddities I've noticed, but let me describe the problem:
I have a machine that was used for the last 8 months and has had no
problems what so ever. Recently, I installed a new graphics card (voodoo
4 4500) and started seeing 'calcru: negative time ...' errors. So while
looking at this, I discovered that suddenly no TSC is shown!
- From dmesg ...

Timecounter "i8254" frequency 1193182 Hz
^^^^^^^^^^^^^^^^^^^
CPU: Pentium III/Pentium III Xeon/Celeron (548.32-MHz 686-class CPU)
Origin = "GenuineIntel" Id = 0x673 Stepping = 3
Features=0x383fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CM
OV,PAT,PSE36,MMX,FXSR,SSE>
Look at one of my other systems, it should look like:
Timecounter "i8254" frequency 1193182 Hz
Timecounter "TSC" frequency 400911562 Hz
With TSC frequency being near the reported clock of the CPU. I read that
the calcru problem has something to do with interrupts and the TSC, and
I've read about the sysctl for changing the kernel timing method. What I'm
wondering, is if there isn't something I can do in the bios or whatnot to
make it act normally again... It should be showing me a TSC and working
correctly. This also causes the time to drift more than ntpd can keep up
at times. I've attached my kernel config & full dmesg output..
Also, the http://www.freebsd.org/FAQ/troubleshoot.html#CALCRU-NEGATIVE
page talks about checking the interrupt setting of the graphics card. I'm
not quite sure what exactly is meant by this, nor would I most likely
realize what it should be or should be modified to be.. Some pointers on
this would be very much appreciated.
Regards,
Matt Heckaman
