Entries here should note the reason for the incompatibility and include a datestamp. Please be as specific as possible about part, model, and revision numbers, including firmware and BIOS versions when relevant.
Don't mention hardware for which there is obviously no driver support; this list is intended to enumerate broken hardware that you would have expected to work ...
- Intel D945GCLF2: Very broken ACPI implementation. Fails to boot the Plan 9 loader; seriously hosed under FreeBSD as well. (2009-12-30 firstname.lastname@example.org)
- Intel DG45ID: ACPI-only, no MP tables, so only one core will be seen. (15 Jan 2010 email@example.com)
- Intel DG45MJ: built-in Ethernet is Realtek and doesn't PXE boot correctly. (19 Jan 2010 firstname.lastname@example.org)
