The system freezes when trying to access the CD Rom (e.g. starting /stand/sysinstall or tying to mount a CD). I had to disable the ata drivers completely (the cdrom is the only ata device, everything else is on SCSI bus) to get rid of these annoying blocks. Hardware has not changed from 4.1, 4.2, 4.3. >How-To-Repeat: accessing the device >Fix: diable ata completely (NOT a real solution) >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
