https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D194727 Matthias Oestreicher <matthias@smormegpa.no> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |matthias@smormegpa.no --- Comment #16 from Matthias Oestreicher <matthias@smormegpa.no> --- I've had the same issue since FreeBSD 11.2-RELEASE with if_uaudio.ko and audio/cmus. Audio device is a 9 year old HRT MusicStreamer II+. When I was on FreeBSD 11.2, the system would suspend, but USB hung up when resumed. In FreeBSD 12.0-RELEASE, the stalled usb drivers will stall before suspendi= ng has finished. I tried to disconnecting the audio device when USB stalls, but that doesn't help Only solution is to ssh into the machine and kill cmus (no -9 needed) and u= sb keyboard and mouse, etc will come back to life and suspend/resume will fini= sh. /dev/ttyv0 is flooded with "Waiting for mixer..." and "Waiting for sound application to exit"=20 This is on USB 2.0 native on Intel Broadwell CPU. I already posted that on the forums in november 2018: https://forums.freebsd.org/threads/weird-xhci-crash-freeze-after-resume-fro= m-suspend.68277/ I wonder if this is specific to a Intel processor/chipset generation, as al= most every new generation of Intel processors/chipsets comes with a new set of b= ugs. Though that's just a guess. I have another computer with a different audio device using if_uaudio.ko, a Asus Impressario BluRayDrive with Xonar audio. This one works fine with suspend/resume on FreeBSD 12.0-RELEASE. I'll move the audio-devices around and post back, maybe that'll give a hint what's the cause. -Matthias --=20 You are receiving this mail because: You are the assignee for the bug.=
