Ubuntu – Booting problems after automatic software update: TPM error and Recovering journal

Last week, after an automatic software update, my PC is having some problems when booting. The PC is a ThinkPad T400 (32 bits) with Ubuntu 18.04.02 LTS. It has dual-boot with Linux and Windows.

A few seconds after starting the boot, the system stops, the screen stay in normal Ubuntu color but with one or two bars in gradient white in the upper half of it. Sometimes after one minute the system itself reboots again, sometimes I need to force the shutdown.
In any case, during the second reboot, appears the following messages:

[1.032407] - TPM TPM0: A TPM error (6) occurred attempting to read a PCR value.  
[1.299927] - TPM TPM0: A TPM error (6) occurred attempting to read a PCR value.  
/dev/sda6/: recovering journal  
/dev/sda6: clean, 324482/1470769 ....

After this message I can see in the screen what system is doing until enter again in graphics mode asking for identification and password and finish the reboot without problems.
Just another information: ist I start a Terminal session and and execute the fsck command, I can see the following message:

artur@artur-ThinkPad-T400:~$ sudo fsck -n  
fsck from util-linux 2.31.1  
e2fsck 1.44.1 (24-Mar-2018)  
Warning!  /dev/sda6 is mounted.    
Warning: skipping journal recovery because doing a read-only filesystem check.      
Superbloco last mount time is in the future.  
    (by less than a day, probably due to the hardware clock being incorrectly set)  
Superbloco last write time is in the future.

/dev/sda6: clean, 324561/14704640 files, 33330696/58808064 blocks

My question is: How to solve this problem?

Shutdown:

Today I could see that the system is doing it normaly. But, still this week I could see the same message /dev/sda6: recovering journal. Before, after software upgrade, as per the computer sound, it seems that, before closing, the processor stops working and the screen still live with ubuntu logo and the dots under it. A few seconds after the computer shutdown definitively.
By the way, I still don't understand why being my computer a Lenovo T400 with 32 bits machine (Intel® Core™2 Duo CPU P8600 @ 2.40GHz × 2), the system was automaticaly upgraded from 16.04.05 to 18.04.1. Is this the cause of these problems?

Summarizing the problem:
To achieve a normal working session in Ubuntu, I need to give two steps.

1. First, in GRUB wait 10 sec start the boot and a few seconds later the system stops with a gradiente strip in upper side of the screen (I can send an image). I have to force a shutdown with power off botton
2. Restart again and in GRUB wait 30 sec and boot starts with black screen and the message:
   /dev/sda6/: recovering journal
   /dev/sda6: clean, 324482/1470769
   but the boot goes on and complete normaly.

SMART Data and autotest

I'm sorry, I've sent in Portuguese. Now I chose the secondary language and it is in English US:
SMART Data and autotest . English

Regarding with the boot on a earlier release of Kernel, I lost that opportunuty yesterday. The good release was 4.15.0-47 Generic and the system updated to 4.15.0.50 Generic and remove the 47. Now in GRUB I have release 48 and 50 and the upgrade didn't solve my problem.
