Description Keiichi Mori 2001-04-18 01:32:15 UTC

From Bugzilla Helper:
User-Agent: Mozilla/4.76 [ja/[Vine,RedHat]] (X11; U; Linux 2.2.16-22 i686)


A machine(Netfinity4500R,Dual-CPU) have two IBM ServeRAID cards(ServeRAID4L
and ServeRAID4H). The both use ips.o driver. 
When the installation of RH7.1 and booting by SMP-kernel(kernel-smp) or
kernel-BOOT, it detect ServeRAID4L first, and next it detect ServeRAID4H.
But when booting by UP-kernel, it detecting ServeRAID4H first.
So the UP-kernel lost root filesystem, and kernel is panic.


Reproducible: Always
Steps to Reproduce:
1.Make a dual-cpu machine which have ServeRAID4L and ServeRAID4H ready.
2.Install RH7.1 to this machine.
3.Boot by SMP-kernel
4.Boot by UP-kernel


Actual Results:  Booting by SMP-kernel is sucessful.
Booting by UP-kernel is failed.
(Because the sequence of detecting ServeRAID cards is difference.)


Expected Results:  The sequence of detecting them does NOT depend on kernel
package.

Comment 1 Arjan van de Ven 2001-04-18 08:15:06 UTC

Is it possible to give "lspci -v" for both (or rather all three) situations ?

Comment 2 Keiichi Mori 2001-04-19 04:59:41 UTC

Here are results of "lspci -v" for all situations. (adding boot option
"root=/dev/sdbx" for up-kernel)

Comment 3 Alan Cox 2003-06-09 15:40:08 UTC

Newer Red Hat uses disk labels to handle volumes being re-ordered. The ordering
dependancy in IBM's ips driver should also be fixed ok nowdays
