I find the line of code near the panic is memcpy().
But the parameters are fine.
One important thing:
The kernel panic only occurs on Mac Pro with memory larger than 2GB,
like 3GB, 4GB,9GB and so on.
If I reduce the memory used to 2GB by boot-args, the kernel panic
disappears.
So my question is:
Can the Mac OS X kernel NOT handle large memory (>2GB) well?
Or the memcpy() function fails sometime on large memory?
What are the addresses you are copying between, and how much are you
trying to
copy at one time?
It sounds suspiciously like you're having 32-bit/64-bit address issues.
