Hi there, I wrote 1st this here: https://github.com/takaswie/snd-firewire-improve/issues/25 But I think it was the bad place, sorry for that. I think this ML is better? My problem in one line: I upgraded my Ubuntu Disco (kernel 4.13) to Ubuntu Eoan (kernel 5.3.19) and I can report my SaffireLE / Firewire doesnt work anymore, snd-bebob reports "discontinuity of CIP" on dmesg... At startup it lights green ok, but no sound is playable, then the lights turn orange (like it is when it's not working), I hear a "relay sound" (a electric clic of a relay), then, the Saffire LE disapears from the sound menu in Ubuntu sound menu. I can see this in dmesg: [ 19.083583] snd-bebob fw1.0: Detect discontinuity of CIP: 10 50 [ 19.746665] snd-bebob fw1.0: Detect discontinuity of CIP: A0 A8 [ 19.846775] snd-bebob fw1.0: Detect discontinuity of CIP: 70 B0 [ 20.335861] snd-bebob fw1.0: Detect discontinuity of CIP: 90 D0 [ 20.856301] snd-bebob fw1.0: Detect discontinuity of CIP: 78 B8 [ 21.312770] snd-bebob fw1.0: Detect discontinuity of CIP: 30 70 [ 21.796716] snd-bebob fw1.0: Detect discontinuity of CIP: 00 40 [ 22.347664] snd-bebob fw1.0: Detect discontinuity of CIP: 00 40 [ 22.818247] snd-bebob fw1.0: Detect discontinuity of CIP: A8 E8 [ 23.306079] snd-bebob fw1.0: Detect discontinuity of CIP: 98 D8 [ 29.544652] snd-bebob fw1.0: Detect discontinuity of CIP: 10 50 [ 30.272090] snd-bebob fw1.0: Detect discontinuity of CIP: A8 E8 [ 30.776168] snd-bebob fw1.0: Detect discontinuity of CIP: 00 40 [ 31.268123] snd-bebob fw1.0: Detect discontinuity of CIP: E0 20 [ 31.766085] snd-bebob fw1.0: Detect discontinuity of CIP: E0 20 [ 32.267903] snd-bebob fw1.0: Detect discontinuity of CIP: 88 C8 [ 32.767989] snd-bebob fw1.0: Detect discontinuity of CIP: F8 38 [ 33.263808] snd-bebob fw1.0: Detect discontinuity of CIP: 78 B8 [ 33.757156] snd-bebob fw1.0: Detect discontinuity of CIP: 08 48 [ 34.258860] snd-bebob fw1.0: Detect discontinuity of CIP: 80 C0 [ 34.755571] snd-bebob fw1.0: Detect discontinuity of CIP: 40 80 [ 35.261252] snd-bebob fw1.0: Detect discontinuity of CIP: 60 A0 [ 35.753980] snd-bebob fw1.0: Detect discontinuity of CIP: 78 B8 [ 36.253547] snd-bebob fw1.0: Detect discontinuity of CIP: C0 00 [ 36.752500] snd-bebob fw1.0: Detect discontinuity of CIP: 08 48 [ 37.255203] snd-bebob fw1.0: Detect discontinuity of CIP: B0 F0 [ 277.760550] snd-bebob fw1.0: Detect discontinuity of CIP: 40 80 [ 278.488972] snd-bebob fw1.0: Detect discontinuity of CIP: C0 00 [ 278.986290] snd-bebob fw1.0: Detect discontinuity of CIP: E0 20 [ 279.485998] snd-bebob fw1.0: Detect discontinuity of CIP: 18 58 [ 279.983838] snd-bebob fw1.0: Detect discontinuity of CIP: D0 10 [ 280.486776] snd-bebob fw1.0: Detect discontinuity of CIP: C0 00 [ 280.979487] snd-bebob fw1.0: Detect discontinuity of CIP: 30 70 [ 281.480952] snd-bebob fw1.0: Detect discontinuity of CIP: 78 B8 [ 281.975413] snd-bebob fw1.0: Detect discontinuity of CIP: 38 78 [ 282.475487] snd-bebob fw1.0: Detect discontinuity of CIP: 60 A0 [ 282.979446] snd-bebob fw1.0: Detect discontinuity of CIP: 88 C8 [ 283.472403] snd-bebob fw1.0: Detect discontinuity of CIP: 88 C8 [ 283.968484] snd-bebob fw1.0: Detect discontinuity of CIP: 68 A8 [ 284.471585] snd-bebob fw1.0: Detect discontinuity of CIP: 30 70 [ 284.562886] usb 3-4.1: reset high-speed USB device number 5 using xhci_hcd [ 284.965508] snd-bebob fw1.0: Detect discontinuity of CIP: D0 10 [ 285.469348] snd-bebob fw1.0: Detect discontinuity of CIP: 68 A8 [ 285.965174] snd-bebob fw1.0: Detect discontinuity of CIP: 20 60 [ 285.981618] firewire_core 0000:05:01.0: phy config: new root=ffc1, gap_count=5 [ 290.103982] firewire_core 0000:05:01.0: phy config: new root=ffc1, gap_count=5 I tried update the kernel with eoan-proposed I know run 5.3.20 and I have the same problem (the trace above is made with 5.3.20. First, I hope I report this the best way, really not sure here. If not, please tell me what to bring (files? logs?) and where (on this list? elsewhere?). I have spare time to investigate anything that could help here.
