Description of problem:
When I run installation program by using CD1, it failed to detect logical 
drive (RAID1) on PERC3/SC (AMI MegaRaid 475). This happens when I tried to 
partition the harddrive, and the error saying "..no valid device..."

How reproducible:

Steps to Reproduce:
1.Connect 2 HDD to AMI MegaRAID 475, create RAID1
2.Insert CD1 to CD-ROM drive and reboot system

What server and BIOS level?  Looks like IRQs aren't getting routed properly, 
and the first obvious symptom is a lack of disk I/O.

usb.c: registered new driver hub
PCI: Found IRQ 5 for device 00:0f.2
IRQ routing conflict for 00:0f.2, have irq 10, want irq 5
eepro100.c: $Revision: 1.36 $ 2000/11/17
PCI: Found IRQ 9 for device 00:02.0
IRQ routing conflict for 00:02.0, have irq 11, want irq 9
megaraid: v1.17a (Release Date: Fri Jul 13 18:44:01 EDT 2001)
PCI: Found IRQ 10 for device 01:04.0
IRQ routing conflict for 01:04.0, have irq 5, want irq 10

Comment 3 Danny Trinh 2001-08-01 13:11:22 UTC
I tested on two servers (PE1300, PE1400), the results are the same. Both 
servers have the lastest BIOS. However, the installation process works very 
well with PERC3/DC, PERC2/DC.

Comment 4 Tesfamariam Michael 2001-08-01 20:06:23 UTC
I was able to install Fairfax Beta 2 on this controller (same firmware and 
config) successfully.

Comment 5 Glen Foster 2001-08-01 20:23:27 UTC
This defect is considered SHOULD-FIX for Fairfax.

Comment 6 Matt Wilson 2001-08-01 21:05:52 UTC
nothing with regard to this controller changed in anaconda; moving to kernel.

Comment 7 Arjan van de Ven 2001-08-01 21:12:07 UTC
I could install it on my Dell PERC3 just fine too, I'll check asap which exact
model it is (it has 128Mb ram)

After installing the megaraid driver, it detects the logical volume but it was 
not given a device name (/dev/sdb). Below is the log message when the megaraid 
driver is installed. 
     megaraid: v1.17a (Release Date: Fri Jul 13 18:44:01 EDT 2001)

I tried this card (perc3/sc) in a 6450 with todays tree.  Anaconda sees the
card, but hangs loading the driver.

Comment 11 Tesfamariam Michael 2001-08-09 19:53:20 UTC
There is an issue with installing onto PE6450 (bugzilla # 50775). Try the work 
around suggested there.

Comment 12 Matt Domsch 2001-08-20 20:34:29 UTC
AMI reproduced the problem, and fixed it.  Go into controller setup during POST,
and press Alt-F to reset to factory defaults.  This somehow clears bad state in
NVRAM.  Dell has sent another failing card to AMI to troubleshoot exactly why it
fails for future fixes.  I'm marking this as closed (from RH's perspective, it's
