Dell S5248F-ON [master branch, boadcom] linux_bcm_knet loads, but ports not available

dmesg:
[ 138.363129] seq_file: buggy .next function bkn_seq_dma_next [linux_bcm_knet] did not update position index
I saved show techsupport output here.
I can help with testing on this hardware when sb have time to look at it. Thanks!

@arunlk-dell i seen that you worked with this switch model. Can you recommend a sonic build where hardware offloading works?
I tested on all broadcom branches, it seems the 202305 is the closest, i can see fan, voltage and leds also seems to work. I can communicate with the 25gb ports. Now i inserted a 1Gbit rj45 to a port then communication works, but the throughput only 0.5Gb and there is 40% system load on the switch, so i think hardware offloading does not work. How can i debug this?
Thanks!

update

after tested all branches the SONiC-OS-202411.768299-645a40f54 was the best.
After some debugging i discovered that the pmon container does not have ipmitools installed. After i installed the package show platform fan started to work.
