Consistent boot time kernel panic

[Shahar Or]

I don't know to provide the necessary crash dump and any other things that may be required to analyze this.

The crash occured consistently on every boot with this kernel.

I'm currently running 4.8.0-32-generic, which I still have installed. It does not cause this crash.

I got this since first reboot after dist-upgrade to 17.04.

BTW, it is not clear how to properly report a boot time kernel panic, so I asked this question:

Do you know what kernel version this panic starts happening in?

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.10 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.

Joseph, regarding what kernel version this panic starts happening in, I know two things:
In 4.8.0-32 it does not.
In 4.9.0-12 it does.

Is this enough information?

I will try the mainline build.

[Shahar Or (mightyiam)]

Crash does not happen with 4.10.0-041000rc5-generic.

[Joseph Salisbury (jsalisbury)]

That is good news.

Can you see if this bug happens with the Zesty proposed kernel?

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Thank you in advance!
