megaraid v1.18d driver patch
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. 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. *** Bug 123289 has been marked as a duplicate of this bug. *** Elliot, 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. Thanks. Tom 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? Yes, AS 2.1 U4 has 2.10.1.1 (one more bug fix than Dell's :^). The problem is that kudzu/anaconda still tries to use the (plain, v1) megaraid driver for that newer card. Patch attached below. Created attachment 101026 [details]
pcitable-megaraid2.patch
Autodetect that the PERC4 needs the megaraid 2 driver.
And reassign. 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. An errata has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
