Hey guys,
I had been running Qubes 3.1 without any issues on my Lenovo T450, since the
support for 3.1 is over I upgraded to 3.2. At first it worked fine but it
stopped booting with newer kernels. It goes on infinite booting cycle.
I looked through Qubes's website Lenovo Troubleshooting pages and the following
group thread https://groups.google.com/forum/#!topic/qubes-users/UXP8RJffpsY,
but was unable to resolve my issue with the information found there.
I currently have XEN 4.6.5 and the following kernels:
4.4.62-12 - goes to infinite boot
4.4.38-11 - same
4.1.24-10 - boots fine
I tried passing noreboot=true to XEN and modeset=0 to Linux as well as
console=hvc0 and earlyprintk=0 as suggested here:
https://groups.google.com/forum/#!topic/qubes-users/UXP8RJffpsY, with no luck
(except it does not reboot of course just freezes with the blank screen).
Could you guys point me in the right direction as to how do I troubleshoot this
issue. E.g. outputs something to the console.
Thanks!
I just purchased a Lenovo Thinkpad X1 Carbon 4th Gen and have been
installing qubes on it over the past few days. I had the same troubles
you are seeing with your T450.
Things were fine with the 3.2 installer and the 4.4.14-11 kernel, but as
soon as I updated dom0 which gave me a newer kernel (I forgot which, but
probably was 4.4.62-12), the system would no longer reliably boot. It
appears it would be trying to show me the screen where it would be
prompting me for my LUKS password but would freeze at a black screen. I
would have to hold the power button down and boot again.
The interesting thing was that maybe 1 out of 20 or 30 tries it would
actually work, making it kind of feel like a timing or race condition of
some kind.
I changed the kernel params, removing "quiet" and adding "text" to try
and get some idea what was happening, however, the info moved on the
screen so fast and the screen totally blanked without me being able to
see anything at all about what was happening. I even tried recording it
with my phone camera and had no luck.
The X1 Carbon does not have a serial port so I can't do any kind of
console logging, and I'm quite sure the issue is happening just before
or right around when the usb system is initialized so I can't really do
any usb serial logging either.
I ran out of ideas trying to troubleshoot the issue and decided to try
another tack.
I booted with the 4.4.14-11 kernel and ran
sudo qubes-dom0-update --enablerepo=qubes-dom0-unstable
This installed a much newer kernel 4.8.12-12, and all my boot troubles
have since gone away. So it seems whatever the issue is with the newer
4.4 kernels it was fixed in newer versions
So maybe you will have luck on your T450 with the 4.8 kernel from unstable.
Good Luck!
Ed
