Description bm 2007-06-02 19:55:45 UTC
Description of problem:

During install IDE drives (connected to the JMB363 controller on a P5B Deluxe
Wifi) are detected as SCSI/SATA, resulting in a message something like "linux
cannot recognize partitions beyond /dev/sda15".  

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

Version used on F7 x86_64 install disk

How reproducible:


Steps to Reproduce:
1. Start install on a computer with an IDE hard drive connected to a JMB363
controller, where the hard drive has more than 15 partitions (11 in extended)
Actual results:

Upgrade from FC6 failed, after ignoring a lot of messages about will not see
partitions, failed when trying to activate swap (I think since swap is on my 3rd
harddrive which actually is SATA and is /dev/sda2 on FC6 but /dev/sdc2 in F7

Straight install results in messages about partitions will not be recognized,
presumably if I install I wont be able to use those partitions

Expected results:

Installs and I can use all the partitions on my IDE drives

Additional info:
I have only tried install on this computer.  I am presuming it is a problem of
the way linux deals with drives attached to the JMB363 controller, but for all I
know it may be a more general problem of IDE drives with more than 15 partitions
if all IDE drives are treated as SCSI.  On FC6 (original kernel and current
2.6.20-1.2952.fc6 kernel) my IDE drives are recognized as hde and hdf (which is
a little strange since I would expect hda and hdb). If I remember correctly when
I was using the vanilla kernel 2.6.20-rc1-git7 it detected these as hdc and hdd).

Unfortunately there is no solution for this problem. The SCSI subsystem
cannot use more than 15 partitions per drive.
