Howdy. We have a handful of IBM servers that use the IBM ServeRAID SCSI card, with the "ips" driver. Problem is, on the NetFinity 6000R 4-way boxen, the standard kernel in 2.2R3, 2.2R4 and Woody does an OOPS when it initializes the card.
The Progeny kernel works fine. I suspect the driver hasn't been updated, and sadly, IBM isn't pushing it into the mainline kernel. The newest driver is 4.80, released 10/5/2001: ftp://ftp.pc.ibm.com/pub/pccbbs/pc_servers/33p2599.tgz I'm currently testing the patch against kernel-source-2.2.19-2.
