AMI MegaRAID 471 card doesn't work in Intel Lion slots 2-10

The megaraid 471 card doesn't work in Intel Lion slots 2-10.
Using kernel 2.4.0-test9-ia64-001004 + megaraid v1.10c driver + IOSAPIC
patch from Asit Mallic of Intel. Card works in slots 1 & 2.
Failure mode is that after ~1400 interrupts, the card stops responding.
This is easily demonstrated on a 4x9GB RAID5 array, one partition
at /dev/sdb1, mke2fs /dev/sdb1. SCSI timeouts will occur before the
PeterJ@ami.com, Asit Mallic @ Intel, and Mike Stephens @ Intel are working
to address this issue.
This defect is considered MUST-FIX for Florence Gold release
megaraid driver v1.13s seems to address the problem. MKJ says it'll be
included in the public beta kernel.
The latest megaraid driver is in and should fix this. It breaks
Azusa, so a better fix needs to be provided, which means that we
need to continue to pay attention for now.
The Azuza issue was with the qla1280 driver, not the megaraid driver.
In any case, BJ released a qla1280 driver today (v3.23) that addresses it.
Oops, cache coherency issue in my mind. Thanks, Matt!
Anyway, 1.13s is included. My thinko.
