The fix will be in 2.6.35.10-82 kernel-2.6.34.8-67.fc13 has been submitted as an update for Fedora 13. https://admin.fedoraproject.org/updates/kernel-2.6.34.8-67.fc13 kernel-2.6.35.11-83.fc14 has been submitted as an update for Fedora 14. https://admin.fedoraproject.org/updates/kernel-2.6.35.11-83.fc14 The server where we noticed this problem is a production machine so I haven't yet had a chance to schedule a window for updates and testing yet. I'm scheduling testing for Feb 11 but since this bug tends to take a day or two to manifest in our experience, I won't have results until Feb 14. Thanks! kernel-2.6.35.11-83.fc14 has been pushed to the Fedora 14 stable repository. If problems still persist, please make note of it in this bug report. The host has been running 2.6.35.11-83.fc14.x86_64 since Feb 11 without any sign of the kernel BUG reported here. Thanks for the fix! kernel-2.6.34.8-68.fc13 has been submitted as an update for Fedora 13. https://admin.fedoraproject.org/updates/kernel-2.6.34.8-68.fc13 kernel-2.6.34.8-68.fc13 has been pushed to the Fedora 13 stable repository. If problems still persist, please make note of it in this bug report. |
Created attachment 475651 [details] 2.6.35-10.69 Description of problem: Kernel BUG during normal server operation. Once triggered, no new NFS mounts are possible, mount.nfs simply hangs indefinitely. The server is F14 x86_64 running autofs pulling maps from LDAP for various NFS mount points. NFS appears to be working correctly up until the crash/bug/oops. Version-Release number of selected component (if applicable): kernel-2.6.35-10.74 kernel-2.6.35-10.69 kernel-2.6.35-9.64 How reproducible: Happens within a day or two of normal operation. Unsure what triggers the bug but it might be related to autofs because I have seen autofs "ghosting" mount points that don't exist in the maps! (negative cache problem?) Steps to Reproduce: 1. Boot server, have users login and begin using system and NFS mounts via command line or nautilus file browser 2. Time passes 2. Kernel BUG appears in logs Actual results: New NFS mounts attempts (manually or via autofs) hang indefinitely until server is rebooted. Network resources basically become unavailable. Expected results: No kernel BUG, NFS and autofs continue working normally. Additional info: Attached is the full /var/log/messages output from "cut here" to "end trace" for one instance of the bug.
