From then on, a seemingly endless sequence of acd0: MODE_SENSE_BIG command timeout - resetting ata1: resetting devices .. done lines are displayed on the screen. >How-To-Repeat: >Fix: Re-jumpering the CD-ROM to act as slave (instead of master) solves the problem. This hint was found in a message from a mailing list, and not on PR kern/36610 (which was recently closed, but the promlem is not solved) >Release-Note: >Audit-Trail: >Unformatted: as master
