Further notes - the A19 bios was from approx June 2013, there is an A21 bios released in 2014 but the few fixes don't seem relevant.
I would *very much* like to have a way of getting some sort of kernel log dump after a failure on the next boot, so I can even diagnose if it is failing the same way each time. Can anyone please direct me to how I should do this? -- 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/1297049 Title: [Dell Inc.
