Thanks for the pointer. Ok, so it would appear, from Bruce's http://docs.freebsd.org/cgi/mid.cgi?20061019110950.X75878 that in the SMP case, the em-driver is not even currently supposed to work with INTR_FAST, which, apparently, is the default... How do I switch to INTR_MPSAFE? Scott states, that it is much slower, than FAST, but I can only compress the data at about 25-30 Mb/s anyway... This close to 6.2-RELEASE, should not MPSAFE be forced by the SMP (with em(4) stating as much)? Thanks! -mi
