Strange Fedora Booting problem: can not mount "LABEL=*"partitions

[Guolin Cheng]

Hi, Stephen and Jeff,

 Thanks. But the problem got debugged&fixed, the answer was post on
fedora-list about 2 weeks ago. 

The problem is: the /etc/blkid.tab file works as an old unappropriate
disk partitions cache for fsck|blkid commands when stystem image is
installed to a different arch (scsi->ide) machine, the old cache will
mislead fsck|blkid at the first run and only the first run, since the
first run will update /etc/blkid.tab file. 

As you know, systemimager and similar methods use a single system image
to clone hundreds of, or thousands of machines very quickly and
reliablely, but this time for Fedora, the /etc/blkid.tab should be
cleared off any existing old disk partitions cache when the
source&destination machines have different types of hard disks.

So, another solution, maybe a better solution, is to patch the e2fsprogs
package, so that the blkid* library routines will ignore the cache
contents in /etc/blkid.tab, just exactly like the existing "blkid -c
/dev/null" does.  


Thanks.

When it "stops", what error does it show?

What happens without the libata patch?

Very very odd --- that really helps, every time?
