On the primary channel there is a Seagate 4GB disk (ST34311A/8.01, ATA/ATAPI rev 4). On the secondary channel there is an ATAPI CD-ROM unit (ATAPI CDROM/V130B, ATA/ATAPI rev 0). On the PCI bus there is a 3COM Etherlink III PCI card (3C590). FreeBSD 5.1 installed. >Description: With FreeBSD 5.1 installed I encountered two problems: 1. The disk IO is very bad, and both dmeg and atacontrol reports that both disk and CD-ROM are running in BIOSPIO (PIO0) mode even though both motherboard and hard disk supports DMA mode. 2. As soon as I tried to configure the vx 3COM Ethernet card the kernel panics. After reinstalling the computer with FreeBSD 4.8-RELEASE all problems are gone: 1. The disk is running in WDMA2 mode (and is much faster). 2. The CD ROM is running in PIO4 mode. 3. The vx card can be configured and works without any seen problems. No change of hardware was done in between. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
