Thanks. The third one is interesting, as it shows :

Sep 16 12:57:39 T600 kernel: BUG: Unable to handle kernel data access at
0xfe295404

0xfe295000-0xfe295fff  0x00d05000         4K  user  r        present           
      accessed                         


So unlike the other cases, this one shows that the area is still read-only and
pointing to the zero shadow area.
Wondering whether for the other ones the area is not allocated to a further
module loader after the failing one.

Are you able to dump kernel_page_tables just after each module load failure
before loading any additional module ?
