Hi everybody,
I'm trying to use the rtl_debug facilities with:
* a Red Hat 7.3 system
* kernel 2.4.18
* rtlinux 3.1 for kernel 2.4.18 (the contributed patch
downloaded from ftp.fsmlabs.com)
All the RTLinux examples seems to work but I encounted difficulties
with the debugging example, see the session below:
------------------------8<-----------------------8<--------------------------
# rmmod hello ; # rmmod rtl_debug
# insmod rtl_debug.o ; insmod hello.o
Warning: loading rtl_debug.o will taint the kernel: no license
Warning: loading hello.o will taint the kernel: no license
# gdb hello.o

------------------------8<-----------------------8<--------------------------
and it hangs here...
Questions:
* is this a problem with this gdb version (and should I downgrade
it to a previously "good" version) ?
* is this a problem with the 2.4.18 rtlinux port (and should I
downgrade to the official rtlinux for 2.4.4 linux) ?
* other suggestions ?
Thanks,
Stelian.
