I am investigating some problems with my
Darwin/OpenDarwin installation, and believe that I have found a problem in
RTClock. I'm trying to investigate further
...
When I boot and run my real-time clock is running
*extremely* slow ... sleep 1 returns in ~45 seconds.
:-(
In digging around I found this same bug repeatedly
reported in FreeBSD, with a fix of adding "kern.timecounter.hardware=i8254" to
sysctl. I'm trying to locate where I can do this same type of operation in
Darwin/Mach ... or can I?
When I boot, this is
what I get:
Kernel virtual space from 0x0 to
0x40000000.
Available physical space from 0x6a8000 to 0x10000000

I am guessing these
errors might be related to my time/clock issues? Anyone have ideas?
I am running the x86 version of code, within Virtual PC 2004
... this is the same platform where the FreeBSD fix worked
...
Thanks in advance!
