During boot time FreeBSD 7.0 current GENERIC hangs while examine the SCSI bus. Only in "Safe Mode" it boots complete into login prompt. I have tested the following cases: normal boot: ACPI enabled and ACPI disabled ------------------------------------------- Kernel messages Waiting 5 sec to settle SCSI device (noperiph: sym0:0:-1:-1) SCSI BUS reset delivered (noperiph: sym1:0:-1:-1) SCSI BUS reset delivered After this the machine hangs, no keyboard entries are possible, only hardware reset Verbose logging: ---------------- Waiting 5 sec to settle SCSI device (noperiph: sym0:0:-1:-1) SCSI BUS reset delivered sym0: enabling clock multiplier sym0: download SCSI SCRIPTS (noperiph: sym1:0:-1:-1) SCSI BUS reset delivered sym1: enabling clock multiplier sym1: download SCSI SCRIPTS After this the machine hangs, no keyboard entries are possible, only hardware reset >From FreeBSD 5.5 I know that now the following message should be shown: (noperiph: sym1:0:-1:-1) change from SE to SE FreeBSD 4.11, 5.3 realese #3, 5.4 and 5.5 run perfect with this hardware constellation. But FreeBSD 6.x and 7.x hang at the described position. I have tested this on eight other systems with two HBAs and they show the same behavior. All were SMP machines and the CPUs were correctly detected. >How-To-Repeat: Restart the system with FreeBSD 6.x or 7.x >Fix: >Release-Note: >Audit-Trail: >Unformatted:
