Description of Problem:
When rebooting, or switching to run level 6, the shutdown hangs after the
line 'Unmounting file systems' is splashed to the screen.
Version-Release number of selected component (if applicable):
pensacola release (aka Enigma?)
Steps to Reproduce:
1. boot system
2. type init 6
Hangs and does not reboot.
System appears to hang when remounting / in the halt script. If one comments
out the remounting of /, the hang does not exist and a forced fsck during
reboot does not occur, but this doesn't seem appropriate.
This is probably due to the mmap fd leak in the ia64 patch; this got fixed last
week in our tree and will be in the next RC. Please reopen if it isn't fixed in
the next RC
