This is a good suggestion, it solved my problem. I was so focused on
this error that I didn't think about this simple solution ^^
Thanks David!

I had same issue before. using gdb 6.3 under x86_64 it was working okay.
Then I jumped to gdb 6.5 under i686 and it worked fine only if I ran as user
root. Now with gdb 6.8 I can not do that. It looks the gdb people has closed
the door to debug setuid programs. So the suggestion is to allo
Hi all,
I'm using a recent kernel (2.6.29.2, compiled by myself) for debugging
purposes. When I launch the guest inside gdb, all is going well until
network configuration. At the moment uml_net is called, I see a
"Permission denied" error inside GDB, which does not appear when I
launch the gue
Hi
I have read and used the gdb on UML tutorials to debug kernel drivers. It
works just fine. But I have not found anything to debug user space programs
inside UML. I am wondering if I want to debug a user space program can i
use gdb inside UML and maybe use mounted directories of the source cod
Hi!,
Where can I find gdb rpm for UML instance. I am using Fedora Core 5 UML and
filesystem from http://user-mode-linux.sourceforge.net. The filesystem does not
have gdb installed.
Thanks in advance.

Hello!
I debug UML kernel 2.6.13-4 using gdb 6.3 with
SIGSEGV pass nostop noprint
SIGUSR1 pass nostop noprint
and with breakpoint set on function that is definetely called during my UML
session (particulary tcp_sendmsg() when I send message using Inet sockets)
and gdb doesn't stop on it!

Hello,
I have a problem debugging the uml kernel using gdb in SKAS mode.
What happens is that right after running the kernel in gdb, it immediately
hits a breakpoint in proc_fs.h. Once I continue, it keeps hitting that
breakpoint a few times, then moves on to break in swab.h etc. Also it's not

I'm having trouble stepping through code after a breakpoint. I hit
