Description of problem:
Motherboard type ....		Abit UL8 
Disk type ....			IBM Deskstar 40gig  IC35L060AVV207-0

Dmesg shows the IDE driver sees the partitions when the IDE driver
loads, but mount complains the filesystem devices do not exist.
"fdisk -l /dev/hda" shows the partition table as expected.
/proc/partitions doesn't show the partitions.
Run "partprobe /dev/hda". The partitions are now visible
in /proc/partitions & the appropriate devices nodes are created.
Attempt to now mount one of the filesystems gives "device busy or
already mounted".
There are no errors in dmesg or /var/log/messages.
"dd" of one of the partitions to a file works & the resulting filesystem
image mounts fine with "mount -o loop".
This disk & motherboard worked fine with FC5.
Linux filesystems reside on a SATA disk.

Version-Release number of selected component (if applicable):
kernel-2.6.18-1.2849.fc6, kernel-2.6.18-1.2798.fc6, kernel-2..6.18-3.rt9.0001

How reproducible:
Always


Steps to Reproduce:
1. mount /dev/hda5
2.partprobe /dev/hda
3. mount /dev/hda5



Actual Results:
1.mount: /dev/hda5 is not a valid block device
2.
3.mount: /dev/hda5 already mounted or /mnt/wind busy

Expected Results:
partition hda5 should have been mounted
