megaraid_mbox and megaraid_mm are the modules for "new generation".
There is no dependency of these modules to megaraid legacy.
Could you please send me the lspci output from the system under test?

but it is ! moreover I have a /proc/megaraid/hba1/ directory structure fully filled with my RAID card, drives, and RAID volumes informations, and I don't hav any entry in sysfs directory tree (witch is the right place for megaraid NG module)
I'd like to understand _why_ this module supposed to be independant from the "new generation" megaraid module needs megaraid NG to be compiled to work correctly ?
I looked over the sources but I didn't found any link between the legacy driver and the newgen one... quite strange !

Subject: [Bugme-new] [Bug 7999] New: MegaRAID Legacy doesn't work with LSI MegaRAID i4 since release 2.00.4
http://bugzilla.kernel.org/show_bug.cgi?id=7999
Summary: MegaRAID Legacy doesn't work with LSI MegaRAID i4 since
release 2.00.4
Kernel Version: 2.6.20
Status: NEW
Severity: blocking
Owner: scsi_drivers-other@kernel-bugs.osdl.org
Submitter: rico@ricospirit.net
Most recent kernel where this bug did *NOT* occur:2.6.14 ?
Distribution:Debian Sarge
Hardware Environment: Asus A7V266 M/B, Adaptec AHA-2940UW, LSI MegaRAID 511 i4
Software Environment:
Problem Description: My MegaRAID i4 adapter, witch works well on linux 2.6.11.6
kernel, doesn't work anymore with newer kernels whereas I use the same config
file (updated by 'make oldconfig') I compared megaraid.c from 2.6.11 and 2.6.20
and I noticed megaraid version goes from 2.00.3 to 2.00.4, so I guess the
problem is here ?
Steps to reproduce: simply compile a kernel >= 2.6.15 with megaraid legacy support !

This is by design ... the i4 is now supported by the new megaraid_mbox
driver. Please retry with that driver.

Damn ! I spent many hours trying many kernel version, but I never
imagined the card support would be translated on megaraid NG !!!
By the way, I added megaraid NG modules on my 2.6.20 and my i4 card is
now recognized... But I can't figure how it works :
hole:/home/rico# lsmod|grep megaraid
megaraid_mbox 35368 0
megaraid_mm 12068 1 megaraid_mbox
megaraid 41704 1
scsi_mod 151980 7
megaraid_mbox,sr_mod,sd_mod,megaraid,sg,aic7xxx,scsi_transport_spi
ho
So if I understand well, the module actively used with the LSI card is
megaraid, the legacy one ! but the mbox and mm are loaded and seems to
be necessary for the legacy driver ?
Never mind, sorry for the inconvenience... and the noise on the lkdml !

Actually, it shouldn't be. megaraid_mbox depends on megaraid_mm as your
lsmod shows, which is correct. However, nothing's depending on legacy
megaraid ... I'm not sure why it's showing as loaded and in use.
