(ENV above is from a different machine with an older install) Motherboard is ASUS P2B-D, BIOS 1013. >Description: After installing latest NVIDIA drivers with SMP enabled, the system locks up completely after starting XFree86. ( Fairly late in the KDE loading process ) Serious damage to the filesystem resulted in every one of five attempts. Completely removing all X and KDE packages didn't restore functionality, so to control variables, I reformatted and reinstalled following each lockup. Following NVIDIA README suggestions, I also tried using the FreeBSD AGP-GART: /boot/loader.conf: agp_load="YES" XF86Config: Option "NvAGP" "2" nv-freebsd.h: #define USE_OS_AGP_GART This time, the system locked during the NVIDIA splash screen. >How-To-Repeat: Install SMP and NVIDIA GEFORCE drivers, in either order. >Fix: Workarounds: 1. Don't enable SMP with NVIDIA GEFORCE drivers. 2. Disable AGP-GART: In XF86Config: Option "NvAGP" "0". This must be done before starting X for the first time with SMP enabled or the system may damaged beyond reasonable repair. ( This will also presumably impair performance, although I don't know how much ) >Release-Note: >Audit-Trail: >Unformatted:
