FC5 Kernel Oops

[carlmle]

Hi,

I am using a fully up to data FC5 on a Dell Poweredge server ( SC1420 ) Dual core Xeon, We use it as a file server.

Linux 2.6.18-1.2239.fc5smp #1 SMP EST 2006 i686 i686 i386 GNU/Linux

Today i was deleting alot of entrys from a database log file via samba and the server hung, spurting out lots to the SSH window I had open.

I rebooted the machine and fetched the log of the crash :

Is this a known Kernel Bug?, Is there anything i can do to report this bug? this is a server that is being used most of the time so I cant do anything to harsh.

Thanks,
Carl.

If it is known it should be in bugzilla. Conversely, if it doesn't seem to be there feel free to report it.
