I use a ASUS CUR-DLS mobo with two P3 at 1GHz, 1GBytes RAM, U160 SCSI equipment and built in 4MB ATI Rage XL PCI graphics. Problem was: Machine freezes spontanously in SMP mode, especially doing a lot of graphics output or simply using Mozilla/FireFox intensively. In single user mode (for update and upgrade purposes) the console freezes after doing a lot of output (while showing what' getting compiled or installed). This 'freezing' does not occur using a Matrox Millenium II PCI! Single user mode works great and stable - but I can not boot machine in multi user mode anymore, the console get stuck with a blinking cursor. That is really weird and seems to be a software problem. Disabling SMP keeps the system running for days with the built in ATI Rage XL PCI graphics, but it still breaks single user mode! I ran into harsh situations while trying to do a buildworld and getting stuck due a dying system when libs got installed! SMP brings down the machine very rapid when doing a lot of graphics! Changing to a Matrox Millenium II, 4MB PCI graphics card keeps single user mode working but freezes the box when coming up into multi user mode! Machine get stuck with a blinking green carret but is still responsive via network. >How-To-Repeat: Use FreeBSD 5.3-RELEASE with PCI graphics and SMP! >Fix: >Release-Note: >Audit-Trail: >Unformatted:
