[Bug 1724657] Re: Boot freeze with Ubuntu 17.10-beta2 on Surface Book

2017-10-26 Thread Chatty
I beliebe the new ucode is saved in the initrd which I didn't use. It mighty 
bei possible to for users having an existing working installation to upgrade 
kernel and ucode (initrd). But Surface Book users starting from scratch with 
the live ISO are still faced with an instant freeze which they can't solve with 
the tools at hand (like additional boot parameter).
So this needs to be resolved by some package maintainer responsible for that 
part of the live ISO. I'll be a willing prey to help testing.

Well, I'm not clear on the limitations of live ISOs but since you were
able to install linux-
image-4.14.0-041400rc5-generic_4.14.0-041400rc5.201710152230_amd64.deb,
it shouldn't be any harder to install the .deb for intel-
microcode-3.20170707.1~ubuntu17.04.0 or newer. I suppose try rebooting
first with just the updated microcode installed and validate that
/proc/cpuinfo shows a newer version, and then reboot with the new kernel
additionally.

Your intel microcode is

freezes immediately.

@Kai: In #3 I already mentioned the latest working 4.12 kernel and the

something in between just point me at it and I'll give it a try.

I already said four days ago that I can but any kernel up to the latest
4.12.14. Any kernel starting from 4.13 freezes at boot. So yes, it's a
regression lying probably in the decompression code.

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.14 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

My Surface Book sports a NVidia 940M (10DE:134B).

With any kernel starting from 4.13 (including yours) I don't even get to
the point of loading modules. When I omit loading of initrd and just do
"linux vmlinuz" & "boot" the system freezes immediately (and my Intelli
Explorer mouse red laser turns off).
