AMD64 install failure on LSI Megaraid.

[Sam Varshavchik]

I'm trying to install Fedora AMD64 0.96 onto a pair of disks in a RAID-1 
configuration, using the Megaraid 320-1 card.  When Anaconda begins 
formatting partitions the cursor becomes very sluggish. The hourglass 
animation goes at, maybe, one third its regular speed, and the pointer 
noticably flickers.

tty4 is spitting out a bunch of "scsi disk error id=0 lun=0 error=40001", 
while all of this is going on.

This continues through the format process, and somewhere in the middle of 
copying the install image I get kicked back to the text mode.  There are no 
diagnostics or error message, except for a blank, generic "install exited 
abnormally", and a shutdown.

Upon reboot both disks in the array are marked as bad.  However the Megaraid 
card shows no media errors on either drive.

If I bring up the disks manually, boot into rescue mode, and use dd 
if=/dev/zero of=/dev/sda[123], I can essentially wipe the entire disk 
without getting the disks flagged as bad.  The physical disks are new, and 
there's every indication that there's nothing wrong with the physical disk.

And I did test the burned Fedora CDs, they are good.

Anaconda automatically brings up the megaraid driver.  I've tried noprobe 
and manually selected megaraid2, with the same results.

The only other detail here is that the Megaraid card is in the 32 bit PCI 
slot.  For some reason I can't boot the machine with the Megaraid card in 
the 64 bit slot.

I'm stumped.  I can write to the entire RAID logical volume using dd, from 
tty2.  But as soon as Anaconda starts loading stuff, errors galore.
