megaraid v1.18d driver patch
Comment 2 Pierre Amadio 2003-10-17 05:41:47 EDT
A workaround that worked here (on a machine installed correctly using previous
ernel) was to install the kernel 2.4.9-e.27smp , changing the megaraid alias
entry in /etc/modules.conf to megaraid_2002, then create a new initrd disk.  
Comment 3 Elliot Peele 2004-05-07 17:49:16 EDT
This still doesn't work in U3 or U4. Is there any chance of this
getting fixed?

I have a couple of Dell 1750s that have this card in them and
installing is a tad painfull since I have to use the original AS2.1
disks to do an install since the megaraid driver from Dell is built
for it and not U4. I am trying to set these machines up to be proxy
servers since the proxy server requires AS2.1.

Comment 5 Tom Coughlan 2004-05-17 14:57:59 EDT

I need a bit more detail on "the megaraid driver from Dell is built
for (the original AS2.1) and not U4".  

In AS2.1 we ship both the megaraid v1.18 driver and various versions
of the megaraid v2 driver. The v1.18 driver is the default, and has
not changed since the original AS2.1.  If it worked for you then, it
should still be working.

Support for new hadrware (like certain PERC4 models) and on-going
maintenance has been put in to the v2 driver. If you need this driver,
then you need to select it manually during the install process (the
noprobe option).

Please let me know more specifically where you are having trouble. 

Comment 6 Elliot Peele 2004-05-17 15:28:27 EDT
Dell supplies a megaraid v2 driver disk compiled for the original
release of AS2.1. I was not aware that the megaraid v2 driver was
shipped in U4. The version that Dell provides is 2.10.1. Is this
available in AS2.1?
Comment 7 Tom Coughlan 2004-05-17 17:25:10 EDT
Yes, AS 2.1 U4 has (one more bug fix than Dell's :^).

Comment 8 Bastien Nocera 2004-06-10 08:39:24 EDT
The problem is that kudzu/anaconda still tries to use the (plain, v1)
megaraid driver for that newer card.
Patch attached below.

Autodetect that the PERC4 needs the megaraid 2 driver.
Comment 10 Bastien Nocera 2004-06-10 08:42:38 EDT
And reassign.
Comment 11 Bill Nottingham 2004-06-28 15:54:48 EDT
This will cause multiple sets of problems:

1) you can't load both drivers on the same box. Ergo, if you have both
kinds of cards, you'll get a system crash.
2) if you upgrade to a later release, you won't be using the default
driver for later releases.

Ergo, this is best handled manually for now.
