I downloaded the latest patches for the gdb and compiled my own version
of gdbmod-2.4

Running gdbmod-2.4 ./vmlinux is fine but when I try the command "info
shared", I got 

"Cannot access memory at address 0x80f13a20"

 

I was able to break in when using "target remote /dev/ttyS0"

 

0xc0457118 in breakpoint ()

Cannot access memory at address 0x80f13a20

 

 

Also, the series file does not contain
gdb-kgdb-module-notification.patch.  I have to manually modify and apply
it.

Before that, the gdb/kgdb seems to be ok but you can't debug loadable
kernel module.

I am using the linux2_6_21_uprev tag for the kgdb patch. 

 

Any help?

Thanks.
