[DragonFlyBSD - Bug #2391] System lock with ahci and acpi enabled on ATI RS690 chipset with SMB600 sata controller
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: 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:
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?
