Description Dick 2001-10-04 04:59:19 UTC
Description of Problem:

The system has a blade in it with a dec21554 non-transparent bridge but it 
is NOT a cpparray SCSI RAID controller.  During installation (at the very 
first) the installation detects the 21554 as a cpqarray controller and 
hangs trying to access a cpqarray (which is not in the system or even the 

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

How Reproducible:

Steps to Reproduce:

1. Use a system with a master and non-system master cpu blade which uses a 
dec 21554 (yes this is Compact PCI, but it should work the same on regular 
pci with a card that has a 21554 which is NOT a cpqarray card).

2.  Put the 7.1 CD in the drive and boot.  Before the initial blue install 
screen prints the installing Anaconda message at the bottom (that never 
appears) a box about the cpqarray appears on the screen and it hangs there 
until rebooted.  If you can put a cdrom on the Non-System cpu blade, the 
problem will happen from that side of the 21554 bridge also.

3. To work around the problem on the master CPU blade, remove the non-
master cpu (with the 21554) before installing.  This is harder to do on 
the non-master cpu since the 21554 is soldered to the board.

Actual Results:

It hangs

Why does this bug report not show up when I seasrch for it on :


Comment 2 Brent Fox 2001-10-05 16:24:32 UTC
Because Interchange is a separate product from Red Hat Linux.  Interchange is an
E-commerce platform, so you were searching the bug reports for that product, not
Red Hat Linux.

I'm not familiar with the DEC 21554, but I can see that the entry in kudzu's
pcitable has the cpqarray driver associated with this card:

0x1011  0x0046  "cpqarray"      "DEC|DECchip 21554"

I'm changing the component for this bug report to kudzu.

Will be fixed in kudzu-0.99.26-1; thanks!
