I’ve been ripping DVDs/BluRays/CDs on my computer for years (I like to have everything on my own media server). It’s been working fine until recently. I upgraded to Leap 15.6 and now frequently start sending error messages to my cosole (and log files):
2025-01-21T21:17:03.630489-05:00 home-sul kernel: [364573.517040][ C0] BUG: workqueue lockup - pool cpus=7 node=0 flags=0x0 nice=0 stuck for 32s!
This message repeat over and over (about every 30 seconds) with the “stuck for” time increasing by about 30 seconds. The value of cpus varies (could be cpus=8, cpus=11, etc.). As this is happening, the system gets bogged down and becomes very unresponsive. A reboot fixes things, but nothing else has worked.
It always happens when I’m using the external DVD/BluRay drive. After this first happened, I thought perhaps the drive had gone bad and I bought a new one (entirely different brand and model), but I just had the same thing happen with this second drive, so I no longer believe it’s an issue with the drive.
I’m running an up-to-date Leap 15.6 system:
uname: Linux my.host 6.4.0-150600.21-default #1 SMP PREEMPT_DYNAMIC Thu May 16 11:09:22 UTC 2024 (36c1e09) x86_64 x86_64 x86_64 GNU/Linux
The system does not have an internal DVD/BluRay, so both the old and new drives are external USB BluRay writers.
Any suggestions for how I can resolve this issue?
Need more details (ripper, another software…).
Try another USB port.
The ripper I mainly use is makemkv . I will try another USB port today. The error doesn’t happen every time so it sometimes takes a while to manifest.
https://software.opensuse.org/package/makemkv
No official repo.
Try to create ISO image with some tool, without converting.
I use makemkv from the packman repo… so yes, no official repo.
I’ll try installing it from one of the alternate community repos as well.
Yes. Sometimes I’m able to rip, other times it fails and the error starts, so it’s not a permissions issue.
So it appears that the issue is related to a known bug in makemkv. The newest version is broken for a number of people. Some details are here:

Nobody there is reporting this workspace queue error, so it’s possible that I’m wrong, but I’ve dowgraded to makemkv and the ripping part seem to be working fine. Thinking back, I’m pretty sure (but not 100% sure) that the workspace queue errors only happened when makemkv was failing to read a disk (which is described in the makemkv forum post). If the workspace queue error shows up again, I’ll update this.
Well, I was wrong. After the makemkv downgrade, I just got the workspace queue error again.
This is with a different USB port than previously used, and a different version of makemkv. So back to square one.
