Hence, as per http://www.supermicro.com/support/resources/results.aspx an update is available for your BIOS (r3.0b). If during your maintenance window, you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and just provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1170087 Title: NFS client hangs after some usage Status in “linux” package in Ubuntu: Incomplete Bug description: We have an Ubuntu 10.04 machine. I mounts a directory (statically, i.e. a line in /etc/fstab) on an NFS server. After some usage, the mount will simply hang. Any attempt to access the mount (e.g. ls /somedir) will just hang, and will have to be kill -9'ed. Trying to mount another NFS export on the same server, or another server, will simply fail (syscall failed). Trying to access the hung export from another machine works fine (i.e. the server side works, this is a client-side problem). This is kernel 2.6.32-45-server. What logs would you like? When trying to do this: rpcdebug -m nfs -s all All I see on an access attempt is: Apr 17 10:47:53 brent kernel: [145406.995318] NFS: revalidating (0:15/2) Apr 17 10:47:53 brent kernel: [145406.995326] NFS call getattr If I do this: rpcdebug - m rpc -s all I get waaaaay too much info. :) This box also serves as an NFS server, but when this glitch happens, the NFS server is unaffected. We cannot do upstream testing. We tried the latest kernel on another machine with the exact same config, and one of our network interfaces would not come up.
