#6922: OpenSound-232d0de71550 KDL's on boot (possible mtrr issue?)

-----------------------------+-----------------------------
This ticket is being split off from my comments made in #6849, as there
may be possible confusion between the various OpenSound packages (which
are not part of build/jam/OptionalPackages, due to concerns of known
issues).
This package of
[http://www.haiku-files.org/files/optional-packages/opensound-
232d0de71550-x86-gcc4-2010-11-26-built_on_r39567-with_extra_dprintf.zip
opensound-232d0de71550]
was built on r39567 with GCC4. It contains extra dprintf()'s to help
pinpoint the exact location of failure.
The failure occurs when
1. The above OpenSound package is installed
1. /boot/system/add-ons/kernel/drivers/dev/audio/* is archived and the
original files are removed
1. On reboot, oss detects the hd audio chipset and triggers a KDL.
The failure is in
