per*_*lex 7 gdb remote-debugging linux-kernel
我正在尝试从内核加载lx 符号。但它一直向我显示以下错误：
(gdb) lx-symbols
loading vmlinux
Python Exception <class 'gdb.MemoryError'> Cannot access memory at address 0xffffffff824fb470:
Error occurred in Python command: Cannot access memory at address 0xffffffff824fb470
现在我成功地能够从同一版本加载lx 符号（不确定这是否是正确的术语），但不知道为什么我可以再加载它。
现在，当我第一次通过 gdb 连接到远程计算机时，它通常显示构建跟踪，如下所示：

现在，当我连接到远程内核时，它会向我显示以下内容：
(gdb) target remote :1235

我注意到构建跟踪 /build/linux-hwe-22QmxS/linux-hwe-5.3.0/arch/x86/include/asm/irqflags.h:61 61消失了（我没有对配置或设置进行任何更改）。
这是我第二次面临同样的问题。第一次，我以为我可能不小心做了一些更改，但随着问题再次出现，这次我很确定我没有做任何更改。
我的.gdbinit文件具有正确的路径。
add-auto-load-safe-path /../../ubuntu-bionic/debian/build/build-generic/vmlinux-gdb.py
我使用以下命令检查源是否正确加载：
(gdb) source /home/../../ubuntu-bionic/debian/build/build-generic/vmlinux-gdb.py
它没有给我带来任何错误。所以，我猜源加载正确。我只是不知道还能做什么。请帮忙。
