Description Robert Macaulay 2007-08-12 17:31:18 EDT
Description of problem:
the halt script calls out to kexec prior to calling. This seemingly causes
access to the root NFS to timeout. When the script runs in debug mode, I get the
timeout when this command is run. Line 220 in /etc/init.d/halt
[ -f /poweroff -o ! -f /halt ] 
followed eventually by NFS timeouts.

The remote client is still pingable. The network isn't gone. If I comment out
the  line right above,
[ -n "$kexec_command" ] && $kexec_command -e >& /dev/null
the reboot works perfectly.

Version-Release number of selected component (if applicable):

How reproducible:
Comment 1 Robert Macaulay 2007-08-14 00:16:16 EDT
Tracked this down to the specifics on the kexec call. 
Initscripts version  initscripts-8.45.7-1

The call to the kexec command at the end of the halt /etc/init.d/halt script
should be changed from

[ -n "$kexec_command" ] && $kexec_command -e >& /dev/null


[ -n "$kexec_command" ] && $kexec_command -e -x >& /dev/null

This leaves up the network interfaces which is important on a NFS mounted root.

This seems to be a dupe of #223932 on Enterprise Linux. Any chance at a backport
of it to FC6 as errata? It's for a netboot FC6 system which is ill behaved on F7

Maybe, will have to see what else is pending.
