Description of problem:
When booting Intel 845PEBT2 based system, boot delays on the last two lines of
the following:


ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
ICH4: IDE controller at PCI slot 00:1f.1
PCI: Enabling device 00:1f.1 (0005 -> 0007)
PCI: Found IRQ 5 for device 00:1f.1
PCI: Sharing IRQ 5 with 00:1d.2

PCI: Found IRQ 10 for device 02:06.0

hdc: IC35L080AVVA07-0, ATA DISK drive
blk: queue c03ca3a0, I/O limit 4095Mb (mask 0xffffffff)
hde: no response (status = 0xfe)
hdg: no response (status = 0xfe)

After the scan timeouts, boot proceeds normally. 



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


How reproducible:
Always

Steps to Reproduce:
1.boot without serial ata drives on intel 845PEBT2
2.
3.
    

Actual Results:  Lengthy delay during detection on IDE devices scanning for
drives on serial ata.

Expected Results:  no delay

Same problem on my Gigabyte GA-7VAXP Ultra :

hde: host protected area => 1
hde: 39876480 sectors (20417 MB) w/418KiB Cache, CHS=39560/16/63, UDMA(33)

I have no SATA devices connected.
This bug makes the kernel part of the boot take 70 seconds instead of 10 
seconds. The BIOS needs much less time to scan for S-ATA devices ( about 10-20 
seconds for both channels )

HW info :
AMD Athlon 900
VIA KT400  north bridge
VIA VT8235 south bridge
Silicon Image sil3112A S-ATA

SW-info:
Red Hat Linux 9 (Shrike)
kernel-2.4.20-8.athlon.rpm

Note:
This bug looks very similar to bug #84401
Comment 2 David Balažic 2003-04-02 06:16:13 EST
According to Andre Hedrick, this 2x30 secs timeout is according to the specs.
He recommends using the kernel parameters hdx=noprobe hdy=noprobe as a 
workaround.

A change for this delay may be implemented, as other drivers don't wait 30 
seconds, neither does the BIOS.

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
