Hi All:
I'll start off by saying that I have read the list archives and freebsd
troubleshooting section on calcru problems, the solutions presented have
not worked in my case. I am at a total loss now.
Background:
This machine has been running for 6 months prior with no problems at all.
The problems started when I added a new video card, however that is not a
change that I can remove, it's absolutely needed for the machine.
I have increased NTIMECOUNTER in the kernel as suggested, I started with
15 and brought it up to 30 in steps of 5. This has had no affect at all, I
have also set kern.timecounter.method to 1 as recommended. This has had no
affect as well.
Interesting parts:
For some reason, the TSC is no longer seen at all! After the addition of
the video card, TSC no longer shows up in dmesg. I see this;
FreeBSD 4.2-STABLE #0: Fri Feb 9 01:40:55 EST 2001
root@epsilon.lucida.ca:/usr/src/sys/compile/EPSILON
Timecounter "i8254" frequency 1193182 Hz
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
CPU: Pentium III/Pentium III Xeon/Celeron (548.32-MHz 686-class CPU)
Origin = "GenuineIntel" Id = 0x673 Stepping = 3
There should be a TSC line under that, like on this machine:
Timecounter "i8254" frequency 1193182 Hz
Timecounter "TSC" frequency 400911205 Hz
CPU: Pentium II/Pentium II Xeon/Celeron (400.91-MHz 686-class CPU)
Origin = "GenuineIntel" Id = 0x660 Stepping = 0
I cannot imagine what would cause TSC to go away, but it happened when I
put in the video card (PCI Voodoo 4 4500). I wont pretend to understand
how the kernel and the timecounters work on a low level, but there must be
something that I can do; other than replacing the video card, which is not
an option at all I'm afraid.
I have attached my full dmesg and kernel configuration, I would appreciate
it if anyone has any ideas, I desperately need the help. Thanks.
Matt
