Janne, good point. There's another possible workaround in certain circumstances. You can also clear the auditd rules which should allow you to continue working on a running system.

This would be done by issuing an auditctl -D, after which you should be able to use the running system, albeit without any auditing. I have various systems with auditing that trigger the null reference without audit rules on the specific pieces. Ie. `chmod 0755 /run/foobar` hangs, even though a system only has a fs write rule for /etc/something; I am not sure that clearing the rules is enough.

I encountered this issue on a Hetzner VPS. It is a KVM based virtual server, not VMware. After rebooting I was unable to login through ssh. Accessing the system from console was possible thugh running many commands resulted in Killed. The kernel stack trace was the same as in the original bug report. There is no quick and dirty workaround documented yet on this bug report, so I add it. Do the following to get your system quickly back to usable state while waiting for the patched kernel: 1) disable starting auditd at boot (for example chmod 000 /etc/init.d/auditd is an easy and ugly way to do it) 2) reboot the system (in my case the reboot command did not work, I had to hard-reset the system) Done. -- 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/1450442 Title: Kernel Oops - unable to handle kernel NULL pointer dereference at (null); Call Trace: [810fb39b] ? audit_compare_dname_path+0x2b/0xa0 Status in linux package in Ubuntu: Fix Released Status in linux source package in Trusty: In Progress Status in linux source package in Utopic: In Progress Bug description: [Impact] Ubuntu VMWare instances running 3.13.0-51 will crash with the following backtrace: [ 12.357276] BUG: unable to handle kernel NULL pointer dereference at (null) [ 12.357886] IP: [8136cb80] strlen+0x0/0x30 [ 12.358457] PGD 230fe9067 PUD 230d5c067 PMD 0 [ 12.359034] Oops: [#1] SMP [ 12.359590] Modules linked in: tcp_diag inet_diag vmw_vsock_vmci_transport vsock ip6t_REJECT xt_hl ip6t_rt nf_conntrack_ipv6 nf_defrag_ipv6 ipt_REJECT xt_LOG xt_limit xt_tcpudp xt_addrtype nf_conntrack_ipv4 nf_defrag_ipv4 xt_conntrack ip6table_filter ip6_tables nf_conntrack_netbios_ns nf_conntrack_broadcast nf_nat_ftp nf_nat nf_conntrack_ftp nf_conntrack crct10dif_pclmul iptable_filter crc32_pclmul ip_tables ghash_clmulni_intel aesni_intel aes_x86_64 ppdev lrw x_tables gf128mul vmwgfx glue_helper ablk_helper cryptd ttm drm vmw_balloon serio_raw shpchp parport_pc lp i2c_piix4 parport mac_hid vmw_vmci psmouse mptspi vmw_pvscsi e1000 mptscsih floppy vmxnet3 mptbase [ 12.364773] CPU: 2 PID: 1718 Comm: fail2ban-server Not tainted 3.13.0-51-generic #84-Ubuntu [ 12.365587] Hardware name: VMware, Inc.
