Re: [mpls-linux-devel] A few problems with ldpd

The really great news is, the auto yum-update caught this mpls based 
kernel updated notice this morning and the kernel update is in sync with 
the latest released fedora 8 kernel cycle ( 2.6.24.4-64).  Further, the 
mpls code compiles and at least boots up with even the latest CVS pulls 
(at least release 2.6.24.4-80).  The even better news, for me at least, 
is this new yum-update build has a compatible nvidia driver, a really 
annoying problem with Lenovo T61 and new kernels. 

The , still, bad news is sysctl is still crashing from, what I believe, 
is with the mpls_procfs.c program at the code listed below.  Following 
the code is the crash at bootup time.  Whats interesti is a home-grown 
build of the mpls code just gets the message "Unknown sysctl binary path". 

I had removed the sysctl code and was going to test the high speed 
interface issue that was plaguing successful testing but will delay that 
and just test with this yum distro of the kernel.
