https://bugzilla.kernel.org/show_bug.cgi?id=43292 Summary: jdb2 lockup with ext3 and nfs Product: File System Version: 2.5 Kernel Version: 3.4 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: ext3 AssignedTo: fs_ext3@xxxxxxxxxxxxxxxxxxxx ReportedBy: flo@xxxxxxx Regression: Yes When using nfs and writing some files nfsd locks up in D state and I get the attached backtraces in dmesg. Once nfsd killed the request that triggered the lockup, the problem will not happen again until the system has been rebooted. (Tested over a period of 20 days) I'm not yet sure if it happens on the first write request or only on some special ones, but I don't really want to reboot my file server and let it hang that often. However, if you can tell me what to look for or what debugging features I should use, I'll be happy to try them. I also didn't yet test if this can be reproduced when writing files directly (without nfs), but I think it would lock up during boot in that case since I'm running a mysqld slave on the system. This started happening around linux 3.2 or 3.3. I've attached the whole dmesg output (including bootup, in case this is related to the hardware).
