Comment 7 MASAO TAKAHASHI 2006-08-11 01:42:19 UTC 
I can't solve this problem.
But I have found a workaround as follows.
When applied this workaround, then the kernel is booted normally.

1. tested fedora core kernel devel version
   linux-2.6.17-1.2545.fc6
2. workaround
   make configuration changes.
   Here
   # CONFIG_PREEMPT_NONE is not set
   CONFIG_PREEMPT_VOLUNTARY=y
   # CONFIG_PREEMPT is not set

Please check this workaround.
Comment 8 MASAO TAKAHASHI 2006-08-24 06:32:32 UTC 
This bug has been fixed after linux-2.6.17-1.2583.fc6.
What's happened ?
