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
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/
