This is a problem if atacontrol has previously been used to set a slower xDMAx speed, the original detected higher speed not working properly. Attempting to mount_cd9660 a defective or incompatible media can do this. So will "atacontrol reinit" or "camcontrol reset". >How-To-Repeat: Can be demonstrated as follows... atacontrol mode 1 Master = UDMA33 Slave = UDMA66 atacontrol mode 1 UDMA33 UDMA33 Master = UDMA33 Slave = UDMA33 camcontrol reset 1 (or atacontrol reinit 1) Reset of bus 1 was successful atacontrol mode 1 Master = UDMA33 Slave = UDMA66 >Fix: >Release-Note: >Audit-Trail: >Unformatted:
