Comment 39 for bug 1396213

I've had a backup of my old Trusty system, and I've built an initrd for 3.16.0-23-generic in that environment. With that initrd, the kernel booted properly. Note, still it takes several minutes for the VG to activate, but it eventually comes up if the kernel waits enough with "rootdelay=300".

Now, kernel bisection would take me to nowhere, as it seems the problem is not with the kernel itself. Any initrd I build under Utopic has the symptom, even older kernels from the 3.13 series.

Could you advise how could I investigate further? I have no idea how could I debug/bisect initrd-s. As I found, the lvm2 package hasn't changed between Trusty and Utopic, so it's not lvm2's initrd scripts themselves.
