Description: At a random time when normally using the PC, the disk is rendered unavailable and any commands run or file accessed has a read error. Poweroff and reboot hang because of unavailable disk. System is completely unusable and needs a forceful restart (pushing the power on button). Misbehaviour happens 100% of the sessions, but with random time to appear (10 minutes to 2 hours after the boot). NOTE: Log harvesting is quite impossible because the disk is rendered unavailable also to system process. Steps to reproduce: 1) Boot with affected kernel and work normally 1) Wait between 10 minutes and 2 hours for the disk to be rendered unavailable 2) Power cycle the PC using the power button Workaround: There are no strict workaround known for the kernel versions affected; once misbehaviour has happened, the only thing that makes the PC usable again is to boot with previous kernel version (e.g. linux-image-4.8.0-46-generic included and lower works as expected). Expected result: Kernel does not render disk unavailable and continuously works.
