Description Krzysio (Chris) Leszczynski 2007-01-26 13:53:03 UTC
Description of problem: The whole machine crashes 30 secs after nfsd is started. Usually it produces no results, just hangs. We tried to attach console on RS-232, but it didn't put anything useful before the crash. We found the client machine that crashes it and firewalled-it-out from the server. Then the server works perfectly but crashes within 15-90 seconds if the selected machine is allowed to connect. The client machine doesn't run any suspicious processes. Before reporting the bug we have change the machine (moving only harddisk) so I don't think it's a hardware problem. Version-Release number of selected component (if applicable): kernel-smp-2.6.18-1.2257.fc5 nfs-utils-1.0.8-4.fc5 (the server has all other components yummed up to the latest version of FC5). How reproducible: Always. We have Fedora Core 5 server with about 100 NFS clients (all fedoras). Previously we had RH70,7.3,9,FC2. It worked perfectly. Now it started crashing every minute (unless nfsd is stopped). Steps to Reproduce: 1. Just start NFS server Additional info: Today it showed something on the screen. We took a photograph with bug report I put 2 photographs here: http://users.camk.edu.pl/chris/fc5-bug-2007-01-26/ Sorry for bugging you with photographs but we were unable to capture this information otherwise. Usually the kernel hanged without even this things The partial text reads: [<53565751>] <0> BUG: spinlock lockup on CPU#0, rpc.rquotad/2494, c0677a34 (Not tainted We tried to use kernel-kdump but it still hanged the whole machine.

Also tried to compile and run vanilla kernel without Fedora patches. The result was same.
