Package: linux-image-2.6.26-1-amd64 Version: 2.6.26-13 After 35 days uptime nfsd died.
System runs with deadline elevator and echo 1 > /sys/devices/system/edac/pci/check_pci_errors echo 1 > /sys/devices/system/cpu/sched_mc_power_savings cpufreq uses ondemand governor I tried to restart nfs-kernel-server, nfs-common and portmap to see if nfs clients reconnect back but without any success. After few rmmod/modprobe attempts I gave up and rebooted server. I will try to get more info if nfsd dies again. dmesg output: Feb 20 23:46:23 atlas kernel: [3371974.871167] ------------[ cut here ]------------ Feb 20 23:46:23 atlas kernel: [3371974.871167] kernel BUG at include/linux/module.h:386!
