Yes; I confused the two, since I rarely do audio stuff at all (I think implementing the ALSA kernel and lib stuff for FreeBSD would not be a bad project for a junior person). So the problem can't be related to the timer changes that Poul was contemplating; therefore it *must* be related to the USB stuff. Maybe it's stomping on an interrupt or I/O address or something. 8-(. > I use /dev/pcaudio to expose the > brokenness of clock code that is not nailed down in the right way. Humor. Ar ar ar. To the original poster: So to fix the original problem, you should disable everything you can (and still boot) except the audio stuff, and then add things back in until it fails; this will identify the problem area, and we can go from there. Uh, it occurs to me that you might be loading your driver as a kernel module; if so, you remembered to recompile it when you recompiled your kernel, right? -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
