Bug 60583

Description of Problem: The dac960 mylex driver fails to load properly on a 
system with more than 2GB of memory.  If left as a module, insmod DAC960 hangs 
and an lsmod from another term shows it to be initializing. If built into the 
kernel dmesgs shows that it loads but subsequent mount commands fail. The same 
configuration will work fine  with 2gb or less (both built into the kernel and 
as a module).


Version-Release number of selected component (if applicable):


How Reproducible: always


Steps to Reproduce:
1. configure system with more than 2gb and a mylex controller
2. insmod DAC960 
3. -or- rebuild kernel w/driver built in and attempt to mount a raid device. 

Actual Results:

lsmod shows the dac960 module is initializing, and the insmod itself hangs



Expected Results:

module should load,  read devices should be available

Additional Information:

if builtin to the kernel the behavior is different, although not correct - 
demsg shows the driver has loaded and fdisk will read and write the table. 
however mkfs or mke2fs hang and attempts to mount any existing filesystems fail


testing was been done using ds20e's one with 3gb of mem the other 2gb. Also a 
ds10 with .5gb.  In the case of the ds20e's the same mylex controller, raid 
set and boot disk were used for testing - the only difference being the memory.
