Open Issues
This is a list of open issues that need to be resolved for FreeBSD
4.9. If you have any updates for this list, please e-mail
re@FreeBSD.org.
As many of these open issues involve merging bus_dma driver changes
from -CURRENT, the busdma project page is
also useful.

| Issue | Status | Responsible | Description |

| FireWire load failure bug. |

Reported on stable@. Did this ever work after the initial firewire commit to drivers.conf in April? If not, is there any reason to not just back out that commit and not have firewire supported during the install? |

Documentation items that must be resolved for 4.9

Handbook should be updated to note that ACPI can be enabled on
4.9 systems. |

Testing focuses for 4.9
| Issue | Status | Responsible | Description |
|---|
| PAE testing |
-- |
More testing should be done with PAE systems to test device
compatibility and performance. In particular, active systems
with 12 gig of ram or more should be thoroughly tested to make
sure the various memory allocation algorithms in the kernel
still scale properly. There were reports of users running out of
KVA space in -CURRENT with large memory machines. |
