Issue #2391 has been updated by Imre Vadasz.
the issue is probably related to the following line from dmesg-verbose: pci:0:20:2: resource reservation failed 0xd0608000 - 0xd060bfff The device pci:0:20:2 is the HDA sound controller. Together with the following line from the "pciconf-lvbc" attachment it seems obvious: map[24]: type Memory, range 32, base 0xd0609000, size 10, enabled The adress spaces for the sb600-sata and the HDA-sound overlap! Probably the same issue as mentioned on the FreeBSD mailing-list: http://unix.derkeiler.com/Mailing-Lists/FreeBSD/current/2008-05/msg00369.html This issue seems to exist at least on both the hp6715b and hp6715s notebooks. I own a hp6715s myself, but I haven't tried DragonFlyBSD on it yet A simple fix would be to check for one of the broken notebook models and choose a different memory region for the sound controller (worked for me on my hp6715s in FreeBSD). Maybe such collisions could be detected automatically? ---------------------------------------- Bug #2391: System lock with ahci and acpi enabled on ATI RS690 chipset with SMB600 sata controller http://bugs.dragonflybsd.org/issues/2391 Author: Joris giovannangeli Status: New Priority: Normal Assignee: Category: Target version: Page fault during boot with ahci and acpi.
