Hibernate Gentoo after update does not work

I have a problem with hibernating my computer. Everything was working before an update. The update installed Plasma 6 and =x11-drivers/nvidia-drivers-550.127.05-r1. The kernel has not been updated. After the update, the following command does nothing: $ loginctl hibernate When I trace it using ltrace, I get the following output: $ ltrace loginctl hibernate setlocale(LC_ALL, "") = "C" elogind_set_program_name(0x7fffb8445a2d, 0x7f266b11bde0, 1, 0) = 0x7f266b135e08 log_setup(0x7fffb8445a2d, 0x7f266b11bde0, 1, 0) = 0 rlimit_nofile_bump(0x80000, 0x7fffb84452c0, 11, 0x7f266b0a9874) = 0 sigbus_install(0, 7, 0, 0x8000000000000000) = 0 getopt_long(2, 0x7fffb8445538, "hp:P:als:H:M:n:o:ci", 0x55aa2480b200, nil) = -1 bus_connect_transport(0, 0, 0, 0x7fffb84453e0) = 0 sd_bus_set_allow_interactive_authorization(0x55aa2482a2a0, 1, 128, 0x7f266b0a928b) = 0 dispatch_verb(2, 0x7fffb8445538, 0x55aa2480b560, 0x55aa2482a2a0 strcmp("halt", "hibernate") = -8 strcmp("poweroff", "hibernate") = 8 strcmp("reboot", "hibernate") = 10 strcmp("kexec", "hibernate") = 3 strcmp("suspend", "hibernate") = 11 strcmp("hibernate", "hibernate") = 0 geteuid() = 1000 on_tty(0x55aa248068c5, 0x7fffb8445a36, 0x55aa2482a2a0, 0x7f266b07986b) = 1 sd_bus_call_method(0x55aa2482a2a0, 0x55aa24806046, 0x55aa2480602e, 0x55aa24807968) = 0xffffff92 polkit_agent_open_if_enabled(0, 1, 0x55aa24808270, 785) = 0 log_get_max_level(5, 0, 0, 0x7f266b096094) = 6 sd_bus_call_method(0x55aa2482a2a0, 0x55aa24806046, 0x55aa2480602e, 0x55aa24807968) = 0xffffff92 log_get_max_level(0x55aa2482a010, 0x55aa2482cd40, 0, 785) = 6 memset(0x7fffb8444f90, '\0', 1024) = 0x7fffb8444f90 _bus_error_message(0x7fffb8444f70, 0xffffff92, 0x7fffb8444f90, 0x7fffb8444f90) = 0x7f266b13520d log_internal(3, 0xffffff92, 0x55aa24807b89, 366) = 0xffffff92 sd_bus_error_free(0x7fffb8444f70, 0x7fffb84443c0, 0, 0x7fffb8444f68) = 0 ) = 0xffffff92 polkit_agent_close(0x7fffb8444f70, 0x7fffb84443c0, 0, 0x7fffb8444f68 --- SIGCHLD (Child exited) --- ) = 0 strv_free(0, 0xfd6b, 0, 0x7f266b091343) = 0 sd_bus_flush_close_unref(0x55aa2482a2a0, 0xfd6b, 0, 0x7f266b091343) = 0 sd_notifyf(0, 0x55aa24806720, 110, 0x7f266b172b20) = 0 polkit_agent_close(0x55aa2482a010, 0x55aa2482bf80, 0x55af7e20817b, 33) = 0 pager_close(0, 0x55aa2482bf80, 0x55af7e20817b, 33) = 0 mac_selinux_finish(0, 0x55aa2482bf80, 0x55af7e20817b, 33) = 0 +++ exited (status 1) +++ Any idea where the problem might be? Everything was working before that update. Hibernating from the start menu doesn't work either. Syslog prints this: # grep loginctl /var/log/everything/current Nov 17 09:47:44 [loginctl] Failed to hibernate system via elogind: Connection timed out What currently goes wrong? The computer does not hibernate. **EDIT**: The command echo disk > /sys/power/state also does not hibernate, although cat /sys/power/state prints freeze mem disk.
