This is not correct.
A correct statement is

Created attachment 133527 [details]
linux-2.6.17-1.2512.fc6 has same problem.
linux-2.6.17-1.2530.fc6 is bad.
Please all patches.
Please rebase all patches to kernel-2.6.18-rc4.
linux-2.6.17-1.2532.fc6 is bad.
This is made by an attached config file.
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
make configuration changes.
# CONFIG_PREEMPT_NONE is not set
# CONFIG_PREEMPT is not set
Please check this workaround.
This bug has been fixed after linux-2.6.17-1.2583.fc6.
What's happened ?
