We need a patch for ext3 filesystems too. :~# mount -o remount,no_mbcache /home mount: /home not mounted already, or bad option :~# mount -o remount,no_mbcache /shares mount: /shares not mounted already, or bad option :~# uname -a Linux fs09k02v-01 3.10.0-ucs215-amd64 #1 SMP Debian 3.10.104-0.1.215.201611190157 (2016-11-19) x86_64 GNU/Linux :~# mount /dev/mapper/vg_ucs-rootfs on / type ext3 (rw,acl,errors=remount-ro) tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) udev on /dev type tmpfs (rw,mode=0755) tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620) /dev/xvda1 on /boot type ext3 (rw,acl) /dev/mapper/vg_ucs-homefs on /home type ext3 (rw,acl,user_xattr) /dev/mapper/vg_ucs-sharefs on /shares type ext3 (rw,acl,user_xattr) /dev/mapper/vg_ucs-tmpfs on /tmp type ext3 (rw,acl) /dev/mapper/vg_ucs-varfs on /var type ext3 (rw,acl) rpc_pipefs on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) nfsd on /proc/fs/nfsd type nfsd (rw) +++ This bug was initially created as a clone of Bug #42983 +++ We need a backport vor 3.2-8 and 3.3 +++ This bug was initially created as a clone of Bug #41054 +++ UCS Version 4.1-1 Ticket#2015091521000246 #24: "NMI watchdog: BUG: soft lockup – CPU#0 stuck for 22s!

I would suggest to mount the ext2/ext3 partitions as ext4 filesystem. Pro: - no kernel patch - faster filesystem (but not as fast as a native ext4) - filesystem is still ext3 compatible Cons: - ... see also e.g. https://wiki.archlinux.org/index.php/ext4#Mounting_ext2.2Fext3_partitions_as_ext4_without_converting
(In reply to Sönke Schwardt-Krummrich from comment #1) > I would suggest to mount the ext2/ext3 partitions as ext4 filesystem. +1: ext3 is unmaintained for a long time and finally was removed with linux-4.3: <http://article.gmane.org/gmane.linux.kernel/2031297> So if you modify /etc/fstab to add "no_mbacache" anyway, you can also change "ext3" → "ext4". Unless overruled with good arguments: WONTFIX
Created attachment 8246 [details] ext3 no_mbcache - UNTESTED! Completely untested!
3.2 is out of maintenance.
Nothing to release.
