Tried to check the integrity: $ sudo fsck.exfat -n -v /dev/sdb1 exfatprogs version : 1.2.9 label: MUSIC sector size: 512.00 B cluster size: 256.00 KB volume size: 2.26 GB /dev/sdb1: clean. directories 2083, files 32997 So it's fine. Just built exfatprogs from main just now (52b816e). For good measure I'll boot up a Windows and retry a file system repair there to see if any errors show up. Curious, I just noticed the volume size appears to be wrong in the above output: /dev/sdb1 501G 390G 111G 78% /mnt/...

Hi folks, I'll give these a try. Sorry for the brief silence. I'll perform an integrity check. I did. I used --follow and had it run in another Tmux window. The excerpt above was retrieved this way. There's about a minute and a half of (no) dmesg output prior to the output at 90829. Will do. Hasn't that been pretty much proven by downgrading just the kernel and friends? And it'd be quite hard to test a clean image, but if the other methods fail to narrow it down, I'll do it. Have to see if I can find one. This system has run for a long time, but debsums should typically be enough to tell if something is amiss, no? So rather than a clean image I'd suggest to attempt another upgrade to see whether that helps, no? I have not. It's a good point, though. However, it'd still be a regression, no? Again, the older kernel simply reads everything and the music plays fine. These are good points. I'll try with cat or so and perhaps mpv as well. If it's indeed an exfat issue there is no relation to the song or mocp. Will report back with some more information.

dear Comose your are in the wrong topic this is not about rk3528 , please look at armbian forum for right please of rk3528 hallo Comose du bist hier am falschen ort , dies hier ist über rk322x board und nicht rk3528 , biite schaue in den anderen Bereichen nach rk35xx (Rk3518 / Rk3528)

I can do that but it does not provide any useful information on the subject in my opinion. Is there a way to downgrade to 25.8.0-trunk.313? According to this post, it might be useful to set the kernel option nvme_core.default_ps_max_latency_us resp. the DT overlay parameter pciex1_gen=3. How can the kernel (cmdline) option be set in Armbian? Regarding the DT overlay parameter pciex1_gen, should I follow this part of the documentation?

So, there is nothing more we can do here I think. Wait for rockchip to correct upstream.
