The AMD chips are undergoing strict evaluation in -hardware since the K6-200 appears to have some serious problems. I'd go with the Intel just for safety. > System boots up to the console just fine; however, as soon as I start > X the system either hangs or reboots after a little bit.

Turns out the multi I/O chip kicks out a spare IRQ 7 whenever the serial port is closed. I had a quickcam installed at the time using that irq, so everytime the port closed it took a picture in space and scrambled the kernel stack, causing a panic. Disabling the qcam driver stopped the problem. > Any thoughts on this problem?

Have you tried hitting <return> twice when the screen blacks out? It may be panicking but you can't see the output. The double return acknowledges the panic and forces a reboot.
