リークのアドレスは 0x803ff250 だと思います

[  264.233489] PC: 0x803ff250:

しかし、addr2lineでアドレスを見つけようとすると

addr2line -e ~/vmlinux 0x803ff250

それはちょうどこの出力を与えました

??:0

ヘルプ/ポインター/ガイダンスはありますか? 私はデバッグが苦手です。事前に感謝します。

you should use the objdump to find out your crashed PC in kernel

i am not familar to addr2line, but it should be usually used at user mode va and used to debugging the user mode program. Not sure if this can finding location of kernel .
