Hello all, I've tried zipjebt workaround in my chromebook and it doesn't work. Sadly it also disables the trackpad so I need an external mouse. I've also tried to have a more verbose log adding the flag verbose to the init line in grub but I had no luck. does some body know how to record what the kernel is doing at boot to pick a few samples that may could help in debugging?
This is my boot command [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-3.13.0-24-generic root=UUID=5a6bd70a-bb11-49ee-b159-0046c358057c ro nolapic verbose splash vt.handoff=7 and the problem still there...

Nevertheless downgrading the kernel will also disble the trackpad support making it a partial solution. To be honest I don't know if the kernel used by L Zhi could be a solution... I've wrote to the user to know if the trackpad issue still present with downgrade. I'm waiting for the answer. Youtube User L Zhi wrote: "ok, in case you do not know yet.. I managed to get around by downgrading the kernel.. using 3.12.17 and it boots in a blink. http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12.17-trusty/ " I wish I could do something else to help in this issue but my knowledge is far away from this. I'm a newbee.
