GRUB loop boot since kernel update (4.13.0.25 from 4.13.0.21)

Asked by Yosha872 on 2018-01-13

Hello I wish to warn about a serious issue (loop reboot after updates on 2018-01-13), I have a laptop on Xubuntu 17.10 (32 bits) used only for web browsing. It’s a old HP 6730s (CPU Intel Celeron T1600. BIOS : 68PZU Ver F.0C 03/12/2009). After one week without admin logging, I have logged in order to do some updates, automatic security updates occured (‘unattend-upgr’) before I could launch myself the updates, the OS asked me to reboot. Now every time I get on the GRUB menu then select 'Ubuntu', the PC reboots !. I have the feeling that this issue might occurs on other PCs, how to provide you some logs ?

From the GRUB menu, when going to ‘Ubuntu advanced options’, I can see that the current kernel version is ‘4.13.0.25-generic’ . When selecting the previous kernel ‘4.13.0.21-generic’ I can run Xubuntu !.

Have you tested your RAM using Memtest86 from GRUB?

I tested today (2018-01-13) the 2 GB of RAM. After 3 pass (2 hours), MemTest does not find any errors (0).

Can you help with this problem?
