Bug#410817: linux-image-2.6.18-3-686: new megaraid driver fails to detect logical drive

Package: linux-image-2.6.18-3-686
Version: 2.6.18-7
Severity: critical
Justification: breaks the whole system

This is the relevant portion of dmesg from the sarge kernel:

I have stuck an  IDE boot drive in the machine (it is in a hosting center
and I don't have any other similarly broken machines), so I can now reboot 
it remotely for experimental purposes if required, and am happy to collect
any information required.

Bug#410817: linux-image-2.6.18-3-686: new megaraid driver fails to detect logical drive

Try to use module megaraid_mbox, instead of module megaraid.

Ok, I reboot with 2.6.18-3 and:

[EMAIL PROTECTED]:~# rmmod megaraid_mbox

megaraid_mm10560  1 megaraid_mbox
scsi_mod  124168  2 megaraid_mbox,sd_mod

dmesg says:

i.e. drive still missing.

Then:

rmmod megaraid_mbox
rmmod megaraid_mm

megaraid   35880  0

megaraid cmm: Unregistered one adapter:0x110
ACPI: PCI interrupt for device :01:02.0 disabled

i.e. the megaraid driver doesn't appear to find  the hardware.  The 
messages in dmesg appear to come from megaraid_mbox (have verified this 
by looking in the source).


Indeed this makes sense, my card has PCI ID 101e:1960, and the legacy 
megaraid driver lists:


alias:  pci:v101Ed9010sv*sd*bc*sc*i*
alias:  pci:v101Ed9060sv*sd*bc*sc*i*
alias:  pci:v8086d1960sv*sd*bc*sc*i*

but megaraid_mbox lists:

alias:  pci:v1028d000Esv1028sd0123bc*sc*i*
alias:  pci:v1000d1960sv1028sd0520bc*sc*i*
alias:  pci:v1000d1960sv1028sd0518bc*sc*i*
alias:  pci:v1000d0407sv*sd*bc*sc*i*

alias:  pci:v1028d0013sv1028sd016Dbc*sc*i*
alias:  pci:v1028d0013sv1028sd016Ebc*sc*i*
alias:  pci:v1028d0013sv1028sd016Fbc*sc*i*
alias:  pci:v1028d0013sv1028sd0170bc*sc*i*
alias:  pci:v1000d0408sv*sd*bc*sc*i*
alias:  pci:v101Ed1960sv*sd*bc*sc*i*
alias:  pci:v1000d1960sv*sd*bc*sc*i*
alias:  pci:v1000d0409sv*sd*bc*sc*i*

so my card will not be picked up by the legacy driver.

The (legacy) megaraid driver includes the 101e:1960 pci id, but this has 
been removed in the etch kernel.  I will try hacking the pci id into the 
legacy megaraid driver.

I can confirm that this works.  I am not sure whether this is the 
correct general solution or whether it's just a bug in megaraid_mbox 
that needs to be fixed.  What's the best way to proceed?
