As far as this issue is concerned I'm one of the lucky ones. I have has sporadic problems with -10xxx errors and the mouse movement. My CPU is a X2 Brisbane 5000+ Black Edition (Unlocked Multi) Stock 2.6GHZ Running at 3.2GHZ with 4gb ddr2 800 @ 886. I'm running a new install of Zephs Rev2 with 10.5.4 (ASU) and modbin kernel 9.4.0. My current uptime is over 2 days not a single issue.

For what its worth i use this to stress test rather than running a bunch of apps, but using this plus a bunch of processes should stress nicely. http://www.soft32.com/Download/Free/CPUTest/4-199513-1.html . The method I use for CPU Test is 32 Instances small and 10 repetitions . YMMV .

PS

2 Days up; and running Transmission (seeding many GB) + the usual's, Firefox will Crash sometimes over night but not resulting in -10xxxx errors anymore with this install.
