Description Tony Camuso 2008-02-25 15:06:08 UTC 
Description of problem:

The HP DL580 G5 PCI architecture is designed for breadth-first sorting.
Specifically, the onboard controller only appears as controller-zero when the
kernel sorts breadth-first.

The controller detect order is critical to work properly with our OS installer
and storage management tools. If the controller detect order changes from
RHEL3->RHEL4, we run the risk of dataloss.

The attached patch puts the DL580 G5 on the pci=bfsort whitelist in the 2.6.9
kernel. This allows us to use this hardware in production.

Comment 7 Alan Cox 2008-05-02 13:52:00 UTC 
Already shiping systems should never have their probe order changed, we risk
breaking existing customers and that is more important than whether the odd
label lines up on the case.
Comment 8 Alan Cox 2008-05-02 13:55:25 UTC 
(and QA please verify that every device that is say eth0 in RHEL 5.1 from a new
install is the same in RHEL52. from a new install, if not please fail the QA)
Comment 9 Ronald Pacheco 2008-05-09 20:20:37 UTC 
Tony,

Has HP tested this?
