GRUB loop boot since kernel update ( from

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 ‘’ . When selecting the previous kernel ‘’ I can run Xubuntu !.

syslog :
kern.log :

How I have get out the issue : by restoring the previous Linux Kernel (from the GRUB menu).

As of today, the kernel has upgraded itself without issue. Perhaps this was a disk (SSD 32 GB) issue.
Now this computer is running Xubuntu 18.04 fine.
uname -r = 4.15.0-22-generic
