Perhaps a "heads-up" e-mail to the freebsd-current mailing list when the first round of commits have settled in? I'm wondering, due to the Nvidia issue stated in this thread, as well as panics I'm seeing using VirtualBox on my computer running HEAD. Thank you so much for taking on this task, all of you, Kip, Alan, and Jeff too -- even though I don't understand all of it, or know about all of the work that goes in to get it done, we all appreciate and benefit from the end result: a faster and better FreeBSD. -BrandonReceived on Mon May 10 2010 - 00:50:33 UTC
