Colin, the modules in `/boot/grub/i386-pc` look funny, and can’t be

Interesting. The file system was created in 2008. ;-) Please find the 
dumpe2fs output attached.

The last reboot before. But I am really confused now though.

     $ ls -ld /boot/grub/i386-pc
     drwxr-xr-x 2 root root 28672 29. Nov 12:13 /boot/grub/i386-pc

But the module files in there are all from August 2020.

     -rw-r--r-- 1 root root   2400 Aug 13 23:00 
'part_gpt.mod-'$'\205\300''u'$'\023\211\351\215\223'']'$'\206\371\377\211\360\350''f'$'\376\377\377\205\300''ur'$'\203\354\004''V'$'\377''t$'$'\030''j'$'\002\350\203\222'

The characters in the file name look like some character encoding. Do 
you know hat that is? UTF-8? The dumped output viewed in an editor shows 
a “Asian” looking characters 胒.

     $ last reboot
     reboot   system boot  5.9.0-4-686-pae  Fri Dec  4 21:10   still running
     reboot   system boot  5.9.0-4-686-pae  Sun Nov 29 17:56 - 17:02 
(4+23:05)
     reboot   system boot  5.9.0-1-686-pae  Sun Nov 29 09:37 - 12:50 
(03:12)
     reboot   system boot  5.9.0-1-686-pae  Sat Oct 31 20:49 - 23:40 
(02:50)

So, I ran

     Nov 29 10:58:55 mattotaupa sudo[2214]:     paul : TTY=pts/0 ; 
PWD=/home/paul ; USER=root ; COMMAND=/usr/bin/apt full-upgrade

and that also touched `/boot/grub/i386-pc`.

The GRUB packages and Linux package were updated according to 
`/var/log/dpkg.log.1`.

     2020-11-29 12:43:21 status installed grub-pc:i386 2.04-10
     […]

So, afterward I was able to reboot without any issues.

But now, it gets really confusing. `last` claims, the system was running 
for four days. But that was not the (power was unplugged in between). I 
also can’t remember the shutdown failing in some strange way. In the 
systemd journal, it’s also recorded as one boot, but messages are 
missing, supporting it was powered off in between.

So, something really strange happened. But looking more into this, and 
that I wasn’t definitely not home on November 29th, 2020 at 17:57, I 
think the system time was just incorrect.

The (old) drive seems alright.

Do you want me to re-install grub to see if it’s a problem introduced in 
Debian’s GRUB 2.04-10?
