Title:
[Lenovo ThinkPad T400] kexec reboot fails
Status in linux package in Ubuntu:
Triaged
Bug description:
After release upgrade to Utopic, when I reboot with kexec (simply with
"reboot" command), my computer cold reboots after "Starting new
kernel" (i.e. I need to get through the POST and GRUB), instead of the
new kernel being loaded. Previously I didn't experience problems with
Trusty.
It matters which kernel I try to boot, while it doesn't matter what
kernel I kexec from, and which version of kexec-tools I have.
I can't boot 3.16.0-25, nor 3.18.0-031800rc6 from any installed
kernels, while I can boot 3.13.0-39 from any kernels without any
problems.
I tried to downgrade kexec-tools from 1:2.0.7-1ubuntu2 (utopic) to
1:2.0.6-0ubuntu2.1 (trusty), but it made no difference.
I have a Lenovo Thinkpad T400. I didn't experience the same on my
other machines, so I suspect some hardware-dependent issue.
