All, There had been a large number of complaints for instability of msk(4) on slightly new Yukon controllers(Ultra, Ultra2, Extreme, Supreme and Optima etc). Latest msk(4) in HEAD seemed to address a couple of long standing issues. So if you are suffering from the instability issue try latest msk(4) in HEAD and let me know how it goes on your box. If you use 8.2-RELEASE, you can use back-ported msk(4) for 8.2-RELEASE at the following URL. http://people.freebsd.org/~yongari/msk/8.2R/if_msk.c http://people.freebsd.org/~yongari/msk/8.2R/if_mskreg.h ============================================================== 88E8040 support: As of today(May 25, 2009) support for 88E8040 was completed and the patch was committed to HEAD. So if you're using CURRENT don't use patches in this directory. The patche(msk.88E8040.patch27) in this directory could be applied to RELENG_7 though. Thanks to all users who helped to write patches. Thanks.
