1. Please describe the problem: After upgrade to newest kernel, system (Dell Precision 5490) doest not power off (or reboot), it just hangs on plymouth screen. Last message is "Reached target: System Power Off" without any error 2. What is the Version-Release number of the kernel: Started to happening after upgrade to 6.16.3, happens also with 6.16.4 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 : System is continuously upgraded since F40 and this never happened before 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: Reproducible always, just power off or reboot and system hangs 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``: Seems to be working fine on 6.17.0-rc3 6. Are you running any modules that not shipped with directly Fedora's kernel?: Nvidia and IPU6 camera drivers from rpm fusion 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. $ journalctl -b --no-hostname -k srp 30 12:00:05 kernel: int3472-discrete INT3472:01: INT3472 seems to have no dependents. srp 30 12:00:05 kernel: srp 30 12:00:15 kernel: BUG: unable to handle page fault for address: 00000000ff78d008 srp 30 12:00:15 kernel: #PF: supervisor read access in kernel mode srp 30 12:00:15 kernel: #PF: error_code(0x0000) - not-present page Reproducible: Always
Hi, just for update, no change with 6.16.5 or 6.16.6
So it seems to be a problem with intel_ipu6_psys. When blacklisted (the module cannot be unloaded, in hangs on busy resource), poweroff/reboot works normally. So probably related to: https://github.com/intel/ipu6-drivers/issues/372 https://github.com/intel/ipu6-drivers/issues/381 (the camera is also not working for me on 6.16+ so there is really something wrong with the IPU6 driver)
Thank you for reporting this. It looks like my colleague Kate has found the root cause and a fix is in the making. This is being discussed here: https://github.com/intel/ipu6-drivers/issues/372
Came here looking for fix to ipu6 camera not working on Dell Precision 5680 with 6.16.7 in Fedora 42 anymore, so same as Petr. Considering https://github.com/intel/ipu6-drivers/issues/372 has been fixed. Is it coming to next fedora kernel ? Shall separate "camera doesn't work" ticket be opened for that?
> Is it coming to next fedora kernel ? Shall separate "camera doesn't work" ticket be opened for that? The problem and thus the fix is not in the Fedora kernel, but in the out of tree drivers packaged in rpmfusion in the akmod-intel-ipu6 package. A fix is available now in rpmfusion's rawhide repo: https://download1.rpmfusion.org/nonfree/fedora/development/rawhide/Everything/x86_64/os/Packages/a/akmod-intel-ipu6-0.0-22.20250909git4bb5b4d.fc44.x86_64.rpm This should should install (download, run "sudo rpm -Uvh akmod-intel....rpm") on Fedora 42 / 43 fine too. I believe that Kate, who maintains the rpmfusion packages plans to push the update to the F42 / F43 rpmfusion repos soon.
Hi, confirming the problem is gone with the new drivers from rpmfusion, camera is working and computer is rebooting without any problems. Thanks.
