With the following config file, whereas the EPSILON version was using some bytes of bss, the RELEASE kernel's bss is so big that I get the "bss overlap, kernel must bzero" at boot time. And if one is trying to put too many things into a kernel, like the sound card driver, MFS, 32 ptys suddenly the kernel is too big to even boot under the 640 KB limit (it happened to a friend of mine). The filesystem seems a little slower too. I've read in the RELEASE announ- cement that the buffer cache was dynamic so it is funny to see the following message when I boot (ok, maybe it's dynamic after boot :-)) And last, how does one use the new sound driver ? I've seen Linux box so I know that /dev/audio can play Sun's .au files but is there utilities like cdsp for it ? Anyway, XFree86 2.0 is running great on it and I'm very happy with it, thanks again for all FreeBSD/NetBSD folks !
