Description Joshua Rubin 2006-07-29 20:17:17 UTC

Most recent kernel where this bug did not occur: 2.6.14
Distribution: Debian (etch)
Hardware Environment: Compaq Proliant DL360
Software Environment: n/a
Problem Description: When built as a module, cpqarray, since 2.6.15, is unable 
to detect arrays. Built into the kernel it works fine. The errors are as 
follows:
cpqarray: Finding drives on ida0
cpqarray: ida0: idaSendPciCmd Timeout out, No command list address returned!
cpqarray: error sending ID Controller

Steps to reproduce: Boot with a Compaq Smart Array card (shows up as "raid 
controller lsi logic/symbios logic 53C1510 (rev 2)" in lspci) and a valid 
array. If the kernel is built with cpqarray as a module that is loaded in an 
initrd, the module is loaded and the array can not be found. If the array 
contains the root partition, the system (obviously) becomes unbootable.

Just to update, I have just found that even if cpqarray is built as a module, 
if the floppy module is loaded before it, then cpqarray finds the arrays just 
fine and booting continues as expected.

I apologize because I do not know if this is a debian or a kernel bug, but 
there is also an active debian bug report at this address:

dirty hack for pollcomplete()

I've attached a dirty hack, it isn't an official patch but if it works it can
be useful to find a better solution.

Joshua, have you tried suggested patch (#2)?
Any updates on this bug, does recent kernel work better?
Thanks.

Hi Natalie,

I no longer have access to the hardware (nor have I for some time now). But we did get things working. As I remember, the kernel in Debian 4.0 (Etch) worked out of the box. Please see the debian bug report listed above to follow that discussion. What I do not remember was if the fix was in the vanilla source or in the debian patch set.

It looks like this patch was the one that fixed things:

Thanks,
Joshua
