cannot submit bugreport: (Error ID: OOPS-ecc8d159658295e41db1cf9fd5387acc)

Since I cannot submit the bugreport in the normal way here is the bugreport I wanted to submit:

Since upgrading to linux-image-4.8.0-34-generic the laptop doesn't boot (black screen).
Forcefully powering it off (by holding down the power button), booting it again and choosing the Advanced/4.8.0-34 recovery option shows an error message about being unable to find the root fs.

Choosing 4.8.0-32-generic from the boot menu works just fine and boots.
I am using full disk encryption, and 4.8.0-34 doesn't even show the password prompt, it goes black right after loading initramfs.
I tried setting 'MODULES=most' instead of 'MODULES=dep' in /etc/initramfs-tools/initramfs.conf, and regenerating it with 'update-initramfs -k 4.8.0-34-generic -u', or purging and reinstalling the -34 version, but it didn't help: it still doesn't boot.

Trying to convert this question into a bugreport (with the 'create bug report' button) gives me similar error:

Timeout error

Sorry, something just went wrong in Launchpad.

We’ve recorded what happened, and we’ll fix it as soon as possible. Apologies for the inconvenience.

Trying again in a couple of minutes might work.

Seems I can file bugs now and I fixed the boot problem (switched compression back to the default gzip instead of lz4 and it works now).
