If you get an LOR, you can check to see if a similar LOR has already been noted on Bjoern Zeeb's page: http://sources.zabbadoz.net/freebsd/lor.html If it hasn't, send him an email with the LOR, and the circumstances under which it arose, as described on that page. Don't forget that there is a lot of debugging code enabled by default under -CURRENT (which at this point is still pretty close to 8-STABLE, and will be until after the release of 8.0, so it ought to be fairly stable). If you feel confident about the safety of using -CURRENT, and want to get the best performance, disable the debugging code as described in /usr/src/UPDATING. > Please count this message as a vote for MFC'ing those cam and > usb changes to 8-STABLE. > I'm guessing that these changes will make it into 8.0, or at least 8-STABLE, fairly soon; but mav@, thompsa@, and re@ will know more. b.
