hello there,
i was also trying to run gdb but when i tried the command that you told it gives the following error:
gdb /linux-*/vmlinux /proc/kcore
GNU gdb Red Hat Linux (5.3post-0.20021129.18rh)

This GDB was configured as "i386-redhat-linux-gnu".../linux-*/vmlinux: No such file or directory.
Core was generated by `ro root=LABEL=/'.
#0 <function called from gdb>
(gdb) q
what could be the possible problem?
thanks in advance
Regards
