Kernel Debugging Guide in the Developer's Handbook
Introduction to Debugging the FreeBSD Kernel presented by JohnBaldwin at BSDCan 2008. Consider this to be recent extensions to the above. Recommended.
ACPI Debugging Guide in the Developer's Handbook. This is a good place to start if you are having problems with identifying hardware. (For instance, for many irq routing, hanging, device not accessible, panics, etc., you might want to see if disabling acpi fixes the problem in question. There are a large number of bad BIOS implementations out there; we put in hacks to work around as many as we can, but more are always needed.)
Information about Debugging with gdb on FreeBSD
Greg Lehey's debugging tutorial. This may not be as up-to-date as some of the above.

A list of committers willing to have PRs assigned to them. (This is in addition to the auto-assigns to mailing lists, and for ports)
