Two days ago I upgraded the kernel to 25.5.1 (6.12.30-current-sunxi) from 25.2.3 (6.12.20-current-sunxi). Since then I have no longer been able to play a certain title (FLAC file) in mocp. In case it's relevant, the title is: "Malukah - Awake (The Dragonborn Comes)".
Symptoms:
dmesg starts showing kernel trace output at 1:43 of the song
mocp finally stalls at 1:52 and it's impossible to interact with it from that point on
Is there anyone here who would be able to provide pointers on how to debug this? I am a developer and I have done some work with Yocto/OE before and wouldn't be afraid to get at this with a debugger. Since it's nicely reproducible, I could switch between those package versions to investigate.
From the trace output it looks as if this is in exfat code. Makes sense, since the song is getting played from a USB key that is exfat-formatted.
Here's the dmesg output with the two traces towards the end. I decided to include a few messages up to the point where systemd starts:
