Hi Lianbo,
The reason for reading the address is gdb try to read .dynamic section
of vmlinux. See the following:
[39] .dynamic DYNAMIC c0000000022d6040 022e6040
0000000000000120 0000000000000010 WA 38 0 8
crash: page excluded: kernel virtual address: c0000000022d6098 type:
"gdb_readmem_callback"
scan_dyntag():
/* Find the start address of the .dynamic section. */
sect = bfd_get_section_by_name (abfd, ".dynamic");
But I guess we cannot block the above code, because .dynamic might be
useful for .ko file reading. Anyway,
the failing doesn't have any side effects to crash, we can simply ignore it.
So for the patch, ack.
Thanks,
Tao Liu
