We get build errors here and some runtime failures here:

https://gitlab.com/cip-project/cip-testing/linux-stable-rc-ci/-/tree/linux-6.12.y

https://gitlab.com/cip-project/cip-testing/linux-stable-rc-ci/-/jobs/16571866335
drivers/net/ethernet/ti/cpsw.c seems to have compile problem:

In file included from ./include/linux/container_of.h:5,
from ./include/linux/kernel.h:22,
from drivers/net/ethernet/ti/cpsw.c:9:
drivers/net/ethernet/ti/cpsw.c: In function 'cpsw_ndo_set_rx_mode_work':
./include/linux/container_of.h:20:54: error: 'struct cpsw_priv' has no member named 'rx_mode_work'

I don't have good diagnostic for runtime problem on arm. Example is here:

Working FDT set to baeea000
Starting kernel ...
(hang)

It is better on x86:
