Subject: PROBLEM: Hang in selftests/netfilter/nft_trans_stress.sh
Hi all,
The `make kselftest` hangs in netfilter/nft_trans_stress.sh test when testing 6.2.0-rc2
(attempted 2 times, waiting half an hour at least):
make[2]: Leaving directory '/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/net/openvswitch'
make[2]: Entering directory '/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/netfilter'
TAP version 13
1..17
# selftests: netfilter: nft_trans_stress.sh
# PASS: nft add/delete test returned 0
# PASS: nft reload test returned 0
The test script seems to be stuck in ping flood:

The platform is Lenovo Ideapad 3 15ITL6 BIOS GGCN50WW running Ubuntu 22.10 kinetic kudu
with XWayland and vanilla mainline Torvalds tree kernel with MGLRU|KMEMLEAK enabled in config.
I am available for additional diagnostics.
Please find the dmesg log, config and the hardware list attached.
NOTE: NMI backtrace reports the kernel as "Tainted", but I am not aware of any modules
force-loaded or proprietary modules.
Thanks,
