1. Please describe the problem: I have a new PC of Dell Pro 14 Premium PA14250. The internal camera is not working. qcam returns errors like "Unable to get rectangle 2 on pad 0/0: Inappropriate ioctl for device" and finally results in "No such device" 2. What is the Version-Release number of the kernel: uname -r 6.17.10-300.fc43.x86_64 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : Not working ever since new fresh install of Fedora 43. 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: Reboot & run qcam 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: Didn't tried. 6. Are you running any modules that not shipped with directly Fedora's kernel?: None. 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag. Reproducible: Always

This seems to be the same problem as bug 2413656, see bug 2413656 comment 1 for a workaround. Looking at your logs you can skip step 6. of the workaround.

Actions checked/done following bug 2413656 comment 1 1~4: checked & okay 5. done 6. skipped 7. qcam works with low resolution. qcam return 4 errors of "Unable to get rectangle" and several warning msgs. (see attached log: qcam-output.1211.txt). Tried camera test with Teams site(https://teams.microsoft.com/v2/) in Chrome browser (chrome://flags/ PipeWire Camera support = enabled) > camera seems to be detected but only black screen comes out (see attached log: journalctl -b 0 -k > kernel.1211.txt)
Created attachment 2140482 [details] Analysis of issue from Claude Code / Opus 4.7 I encountered this same issue with my new laptop for work and and was told by internal support to open a report, but first searched and found this. Will try workaround, but wanted to assist if possible by submitting analysis from Claude, in case it helps.
Ah, I will not be performing the workaround, as this is a system maintained by my employer and kernel/driver hacking won't mesh w/that. Will wait for a patch through standard update channel. Thanks.
I opened a new bug report for the same issue to avoid cluttering the existing one. My hardware may be slightly different, and the workaround isn’t working https://bugzilla.redhat.com/show_bug.cgi?id=2477461
