Description exarkun 2023-02-18 20:45:14 UTC
1. Please describe the problem:

Running NFS server on fedora 36 on a Raspberry Pi 4 Model B Rev 1.4.  
When an NFS client accesses an export, the kernel panics with:

Unable to handle kernel paging request at virtual address 002fffff00000008

2. What is the Version-Release number of the kernel:

6.1.11-100.fc36.aarch64

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 

Yes, it worked up till the kernel for fedora 36 was updated to  kernel-6.0.5-200  I have tested each new version of 6.x since this issue and it has not been resolved yet.

Kernel 5.19.16-200 does not exhibit the issue.


4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

Boot with kernel 6.x
Setup an NFS export.
Access the NFS export from an NFS client


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``:

I installed the rawhide kernel and my system would not boot up.
kernel-core-6.2.0-0.rc8.20230217gitec35307e18ba.60.fc39.aarch64

6. Are you running any modules that not shipped with directly Fedora's kernel?:

No

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.

I think this is a duplicate of 2148276 and not Pi-specific.

Comment 3 exarkun 2023-03-02 18:22:12 UTC
Does look the same
