[Kgdb-bugreport] kgdb can't connect

[Michel H. <Mic...@ma...>]

Hello, 

I have the following problems/comments to report.

1) Problem with early_param ???

If have the following error when trying to connect to target.

(gdb) target remote /dev/ttyS0
Remote debugging using /dev/ttyS0
Couldn't establish connection to remote target
Remote failure reply: E22

Andrew Grover posted a message on the same subject on 2004-07-29.
Apparently, Mithlesh Thukral took care of a fix, but it now seems to be
broken again.

I am using a clean 2.6.13 kernel from kernel.org that I patched with the
kgdb patch package available on SourceForge for 2.6.13.

If I let the system boot without kgdbwait parameter, I can then connect
later on once the kernel is running.

2) CONFIG_KGDB_CONSOLE hangs the system
When I enable CONFIG_KGDB_CONSOLE, the system hangs at "Uncompressing
Linux..Ok, booting the kernel" 

3) Clarifications suggested for the documentation
It is said in the README of the patch package that architecture
dependant patches are only required for their respective architecture.
In fact, all the patches are required for the set of patches to apply
successfully.
