dmesg

I just installed kernel 3.19 generic amd64 on my Ubuntu Vivid. dmesg shows 125 lines like:

[    7.058694] Request for unknown module key 'Magrathea: Glacier signing key: 007271576a09d86ef244371b0633e47abb75b89d' err -11

This line does not appear with (all amd64):

3.19 lowlatency amd64
3.19-rc7 generic amd64
3.19-rc7 lowlatency amd64
3.18.0-12-generic

Running "ubuntu-bug linux" leads to the message:

"It appears you are currently running a mainline kernel.  It would be better to report this bug upstream at http://bugzilla.kernel.org/ so that the upstream kernel developers are aware of the issue. "

... so I'm reporting here.

Full dmesg attached.

Thanks!  This simply means it can't find the signing key for your modules.  I'm not quite sure how you ended up without the key used to sign the modules (unless somehow it's picking up Ubuntu modules).

Can you please attach your .config?  And how did you build and install the kernel?

Thanks!
Rusty.

Thank you for your followup.

I got the kernel deb's pre-built from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-vivid/

So something 'has gone wrong with building those kernel debs?

Definitely....

I just installed the kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2015-02-10-vivid/ and ... no more 'Request for unknown module key 'Magrathea: Glacier signing key:' stuff in dmesg. Just a nice "Loaded X.509 cert 'Magrathea: Glacier signing key: 1bd164eaa2a1eb7edaab06474ef1a15d1a8315f8'"


Thank you for your explanation and help
