@Jim
The os is Stlinux (Cpu Sh4) . Welcome! | STLinux and it run with busybox.
2.6.23.17
in this article it says , about kernel debugging with stlinux :
Debugging the kernel | STLinux

but i am not sure , if my stb's kernel debugging is enable (i mean , the stb's kernel had compiled with the feature of kernel debugging) but this is not prevent me , since i had installed Stlinux in my pc , if i could achieve to enable System core dump of my stb , maybe i could debug it in my pc , how could i get system core dump with my stlinux's stb? if it would be any link , i appreciate and do it as link instruction...
Does Tail command could be helpful for my case?

P.S: for debugging purposes , i had run my STB , via NFS with the log (shown in Terminal)

kloadsrv(8)						      System Manager's Manual						       kloadsrv(8)

NAME
kloadsrv - Kernel load server SYNOPSIS
/sbin/kloadsrv [-V] [-f] [-d debug-level] [-log logfile] [-p kernel-package-name] [kernel-object-filename] FLAGS
Displays the version of the kloadsrv command. Causes kloadsrv to remain in the foreground. Specifies the level of debugging information. The debug-level is a small integer. Zero disables debugging. Nonzero values from one to higher levels cause kloadsrv to display various log messages. Specifies that the debugging information is to be sent to the specified log file. Logfile should be specified as a full pathname. By default, the debugging information is sent to /dev/console. Specifies the name of the default kernel package. DESCRIPTION
The kloadsrv command loads kernel modules into the kernel. It is typically started during system startup. If you omit the kernel-object- filename from the startup command line, the kloadsrv daemon uses the running kernel. During its initialization, kloadsrv builds a list of kernel symbols that device drivers can use. Moving or overwriting the kernel object file in single user mode can cause this list of symbols to contain inaccurate addresses. The addresses in the list reflect the addresses in the new kernel, not the addresses in the booted kernel. Each symbol exported by the kernel belongs to the kernel package. This package is named kernel, unless you use the -p flag. Once kloadsrv has successfully initialized itself, it puts itself into the background and enters its server loop, where it waits to receive and respond to load requests, unload requests, and query requests. If you specify the -f flag, the command remains in the foreground. RELATED INFORMATION
Commands: cfgmgr(8), sysconfig(8), sysconfigdb(8) delim off kloadsrv(8)
