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?

I've also seen in the youtube link that downgrading the kernel fixes de issue. 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.
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- b159-0046c35805 7c ro nolapic verbose splash vt.handoff=7
and the problem still there...

"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://
I wish I could do something else to help in this issue but my knowledge is far away from this. I'm a newbee.
