Thanks a log for your hard work! one thing I would like to report, I had an issue with pulseaudio with latest kernel as of today. On thing specific my laptop internal audio is actually uaudio which makes it maybe a bit specific. I have an application which queries pulseaudio every minute to get the status of the mixer, this application starts pulseaudio if not present. It starts it a first time, the process run but seems to hang somehow and becomes unkillable (even via kill -9) the backtraces shows: mi_switch+0xba _cv_wait+0xf8 getchns+0x9f dsp_poll+0xc4 devfs_poll_f+0x7d kern_poll_kfds+0x3f6 kern_poll+0x9d sys_ppoll+0x70 amd64_syscall+0x109 fast_syscall_common+0xf8 with a kernel from 10 days ago this wasn't happening. if I change the PCM_WAIT() macro to use cv_wait_sig then everything seems to be back to normal. I don't know if that rings a bell or how to help you more on debugging this. Best regards, Bapt
