Debian's lenny repositories are now featuring linux 2.6.26 - nice! I updated my Acer Extensa EX5620-4025 last night, but I'm still having some issues with hal and wifi. :-(
The mini-pci-express chip is causing kernel oops, and I have no idea how to deal with that, other than submitting the error report.
Besides these issues, I've been leaning a ton about pfSense, ALIX boards, and hal in general. Good stuff indeed.
