First, I hope I report this the best way, really not sure here.
This list is for this purpose. Thanks for your report and I apologize your inconvenience.
Don't apologize, bugs happens.
I thank you very much for this fast answer.
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.
The messages in syslog means that your Focusrite Saffire LE transfers isochronous packet to your system with discontinued sequence number.
OK.
But subtraction of the counter (e.g. 0x20 and 0x60 in the last line) always results 0x40. The former(=0x20) is expected but the isochronous packet includes the latter(=0x60). I think it's any possible bug of ALSA IEC 61883-1/6 packet streaming engine and check it.
OK.
I'll install Eoan kernel and test my devices. (but I don't have Saffire and Saffire LE...) I'd like you to wait for my test report.
What I can say is that with kernel 4.13 under Ubunto Disco everything was fine :-(
I can say too I never had to plug external power, the power by the firewire cable has allways been enough for it. And this is still working on Windows 10 (I have dualboot on my computer, but only do audio things on linux, mostly with Ardour).
Thanks
Thanks to you !!
I'll be waiting for your tests. Be sure to ping my anytime you need info, log files or whatever.
I'm "jpa" on irc.freenode.net, connected worktime (~9am ~8pm UTC+1)
Cheers,
Takashi Sakamoto
