test_destroy_dormant_* are failing on Ubuntu 22.04 with kernel 5.15.0-60-generic

[e-kov]

Note: This bug is a candidate for ice box because it's reproducible on the single machine and not reproducible on other envs with the same Ubuntu 22.04 and 5.15.0-60-generic kernel.
Logs:
failng_tests.log
dmesg.log

Problems:

1. System call table is not located. However kernel-config.h contains not empty SYS_CALL_TABLE_ADDR value.
   dmesg:

[  146.205629] elastio-snap: failed to locate system call table, persistence disabled: -2
[  146.205631] elastio-snap: couldn't hook the syscall table: -2

2. Probably due to this issue with system call table test_destroy_dormant_* and test_reload are failing:

Some other tests are failing too probably as result of the previous failures. The full log is attached above.

Also this bug is reproducible on a bit newer kernel 5.15.0-73-generic and it's NOT reproducible in our Ubuntu 22.04 vagrant box. It has already Linux kernel 5.19. But the issue is not reproducible after kernel downgrade to ``5.15.0-73-generic. Also the issue is not reproducible on my env with the newer 5.19.0-43-generic`.
