Description of problem:
When the pcmcia services start, they properly recognize an external scsi
disk attached thru an apa1480a (aix7xxx_mod) but they do not apparently
read the partition table (or similar). As a result, mounting a partition
using the label never works until whichever operation is performed on the
scsi bus.

Ie:
boot the machine and get:
  Vendor: SEAGATE   Model: ST318416N         Rev: 0010
  Type:   Direct-Access                      ANSI SCSI revision: 03

blk: queue c1ba9018, I/O limit 4095Mb (mask 0xffffffff)
scsi1:0:2:0: Tagged Queuing enabled.  Depth 253

try to mount the second partition of the harddrive (label /disk2)
defined in fstab as:
LABEL=/disk2    /disk2  ext2    user,noauto,dev,exec,suid 0 0


[root@pceet215 log]# mount /disk2
mount: no such partition found

make a "fake" operation on the scsi bus, ie
 hdparm -tT /dev/sda
or
  fdisk /dev/sda
or whatever else, then you see on the logs:

Nov 11 16:03:11 pceet215 kernel:  sdb: unknown partition table

and from now on everything works fine, ie:

[root@pceet215 log]# mount /disk2
[root@pceet215 log]# df /disk2
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/sda2              4901956   3860424    792528  83% /disk2

It seems part of the initialization is delayed and does not occur until an
operation is issued. this is also causing problems with the cdrom and the
MO unit. The problem is there in RH7.1 as well, exactly the same


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.boot with a scsi HD attached to a scsi pcmcia controller with a partition
with a label
2.try to mount that partition thru the label and not the device
3.make whichever operation on the scsi bus and try again
	

Actual Results:  The partition is not found until some other operation
successfully completes on the scsi bus (not necessarily on the same disk)

Expected Results:  the partition should mount fine

Additional info:

Dell latitude C800 with an Adaptec APA1480a with a scsi HD, a MO hd and a
CDR/W (see above), running RH7.2 with all updates. Same problem with the
same hardware under RH7.1
