Bug#516376: kernel BUG at include/linux/module.h:386! | nfsd crash
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:
