[cite] emaxxx:[/cite]Hi guys.
I had this issue (mouse jumping and reboots after hours of bittorrent and heavy download overnight) a while ago (10.5.1) and after reinstalling Leopard many times, replacing kext and hardware components like usb2 and network i found It could probably be related to APIC implementation in BIOS. What led me to this was the fact that my crash happens overnight or after waking up from the screensaver. So I tought about ACPI problems. All of this only happened when running both CPUS. With cpus=1 all worked well. Searching around I found that some users had issues even in windows with heavy overclock and dual core AMDs related to APIC Advanced Programmable Interrupt Controller that in dual core processors could led to some stability issues. The solution for me was to select the 1.1 version in Bios and not the 1.4 (default). Also I set the IRQ manually. I have a NF4 DFI Ultra-D motherboard. Hope this helps.

This solved my issues, too!

I actually looked into my BIOS for the APIC setting, and mine was grayed out for some reason. It also looked like I would only have the choice between "on" or "off" ...so I don't think it would have let me pick a version number, like emaxxx said. So no go for me.

I have 4gb ram and i had this same problem. I had to turn OFF "Memory Hole Remapping" or Remap Memory Hole some BIOS are different. I found this option in my DRAM setting menu where i set CAS/RAS/TRCD /etc..
