FreeBSD 4.6 crashes with kernel panic as soon as sysinstall tries to probe the hardware during installation. Or if 4.6 is installed by some work-around, it crashes with kernel panic if sysinstall is run and there is more than one IDE unit attached. Or it crashes directly at boot-up when the system tries to mount disk if more than one IDE unit is installed on the primary channel. Motherboard: ASUS P55T2P4D with dual-pentium 150MHz. IDE-chip: CMD 646 There has been no problems with FreeBSD 4.5. If sysinstall from 4.5 is used for 4.6, FreeBSD seems to be installed correctly. Yes, the floppies and the installation CD with 4.6 has been successfully used for installation on another computer (in that case with one harddisk on primary IDE channel and on CD player on the secondary IDE channel). Yes, I do have another problem. Even though both the disk and the IDE chip support DMA, the disk is mounted in PIO mode. The system tries DMA mode, but falls back to PIO mode after serveral trials.
