Comment 0 for bug 1683275

Hi guys,

some days ago, I have run the command apt-get dist-upgrade and my system (Virtual machine Hyper-V) install the latest kernel 4.4.0-72-generic. Yesterday, I restart the system and detect, that the kernel unable to boot :( Another boot, I selected the kernel 4.4.0.66-generic and the system works perfectly.

Today, I found the resaon for that. While booting 4.4.0-72 I see the follow error:

Dev sdd: unable to read RDB block 0

This partition is an gpt device and it works perfectly with kernel 4.4.0-66-generic. The device is ok and the smart values are good.

I know that´s not enough informations but I don´t know how I find the informations about the last crash boot process.
