I built my own image with d4f5b37a08d64dce5f9d690f381b0e1c3f253913 on r64-emmc branch.
after i enable hwnat via luci firewall options, kernel will panic(oops) randomly.
it will always crash because “Unable to handle kernel paging request at virtual address ffffff883e35ffa0”, the address ffffff883e35ffa0 is always the same.
obviously nbd’s code is too new that i cannot search out any things about this kernel panic on google
anyone have idea about this?
I guess hnat is not ready yet. Have you the oops without it? Can you give a full traceback of the oops?
It’s only affecting hw nat offload function.
it’s midnight here, i just closed my computer few minutes ago.
I will submit that full log tomorrow, if you are interested, (in my memory) the stack is
fffffffxxxx(no symbol, seems to be a strange address? maybe stack is corrupted?) mtk_flow_offload (static function in driver/net/ethernet/mediatek/mtk_soc_eth.c) on calling next before return, finally oops at mtk_flow_offload_add(at driver/net/ethernet/mediatek/mtk_offload.c ) function line “rcu_assign_pointer(eth->foe_flow_table[rhash], NULL);” in offload flow deletion routine.
The oops instruction is last asm of that c code, ldr x(num),[x0]
Maybe it’s better to create an issue on openwrts github.
It seems to be working in a limited fashion for me. Try:
wifi down
echo 1 > /sys/kernel/debug/ieee80211/phy0/mt76/dbdc
wifi reconf
You should then be able to see “Band 2” with the command: iw list
yes, create an issue on github may be good, i just wonder if anyone have encountered this problem.
if i am the only one, this may not be a kernel bug, but related to my own build environment. if anyone else can reproduce this, it must be a kernel bug.

Thanks for report and trace/objdump (unfortunately i have not enough knowledge to understand it). Maybe data needs to be aligned to 4k pagesize (address is not)?
thanks for reply, seems cannot work
thank s for you help.
I get your branch try to build the image, but I get the error when boot it always cannot mount the rootfs. do you meet this issue before?log.txt (5.1 KB)
thanks, Water
Did you select Banana Pi R64 (rootdisk) as device?
@graphine thanks for reply. not I select Banana Pi R64 as device, will try follow your advise!
thanks, Water
still the same error.

Did you write the fullimage?
dd of=/dev/mmcblk0 bs=512 seek=0 if=openwrt-mediatek-mt7622-bpi_bananapi-r64-rootdisk-ext4-fullimage-emmc.img
yes, use the command: dd of=/dev/mmcblk0 if=openwrt-mediatek-mt7622-bpi_bananapi-r64-rootdisk-ext4-fullimage-emmc.img
can you show which partitions are recognized and mmc-parts from bootlog? do you have any mtd-options set in cmdline?
hi frank, no, it boots from devnum=0(emmc) and I didn’t change options. log.txt (22.6 KB)
thanks, Water
I’m not sure why this is happening for you. Anyone else having this issue?

Hi graphine. You create image for emmc, but can you create image for sd card? Because sometimes need load from sd.
I will try to do that, needs different preloader/gpt and small changes in dts.
