Phil Richardson, as per http://www.dell.com/support/drivers/us/en/19/Product/optiplex-755 an update is available for your BIOS (A22). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything?

[Bug 1114673] Re: mount.cifs occasionally causes GPF error/kernel panic when mounting at boot [crypto_larval_kill+0x2b/0x90]
This bug is not confined to cifs mounts in fstab. I can get a kernel crash if i mount it manually but too soon after boot. I have a rather fast boot since i am running on an ssd and lubuntu so i think there might be some timing. issue, either network isn't properly up or some other process is doing something fishy. To me it also sometimes occur if the connection to the smaba server is interrupted somehow. We had a maintenance of the VPN tunnel between two sites and that killed the mounts with fatal results. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1114673 Title: mount.cifs occasionally causes GPF error/kernel panic when mounting at boot [crypto_larval_kill+0x2b/0x90] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1114673/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1114673] Re: mount.cifs occasionally causes GPF error/kernel panic when mounting at boot [crypto_larval_kill+0x2b/0x90]
To add, this kernel caused me to pain. On removing it, it failed during removal an a spontaneous reboot left me with a system that would not boot as it could not find the kernel. As it's headless, finally managed to get on an boot to old kernel. When loaded, completed the removal and rebuild Grub. Also noted that CIFS had mounted correctly. Rebooted again to get verify clean boot. All as expected, all mounted. Ran apt-get to install the updates since the 3rd, but no kernel due as already on latest. Lo and behold, the failed to mount on boot. This seems to be a pretty regular pattern in that reboots following updates, causes the problem. Right now again, system load is climbing at a linear pace and not I have a few mins spare to investigate, there are no processes using resource. There is absolutely nothing queueing to cause this load to increase. I an however see the login prompt, which is warning me mountall as disconnected from Plymouth. Rebooting out of the problem again and it took 4 reboots to return to normal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1114673 Title: mount.cifs occasionally causes GPF error/kernel panic when mounting at boot [crypto_larval_kill+0x2b/0x90] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1114673/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I will try, but that page is by far the most confusing thing I have ever read. I get the process of conducting the install, of which files I need due to arch and stuff, but the process of determining which is the upstream one to use ?!?! Given I am on 3.2.0-37.58, does that mean I use the one in the current directory of daily, or use the lookup take to use the next one 3.2.38?

[Bug 1114673] Re: mount.cifs occasionally causes GPF error/kernel panic when mounting at boot [crypto_larval_kill+0x2b/0x90]
*** This bug is a duplicate of bug 1070256 *** https://bugs.launchpad.net/bugs/1070256 Of note, it took three systems reboots to allow CIFS operation following report generation. CPU load was spiralling out of control an with each passing second was picking up at a linear pace. Unfortunately, I have not debugs what process was requiring so many resources before rebooting out of the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1114673 Title: mount.cifs occasionally causes GPF error/kernel panic when mounting at boot [crypto_larval_kill+0x2b/0x90] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1114673/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
