aacraid hangs at boot on linux-2.4.27-pre1 20 second delay at lilo prompt makes it succeed

[Jeffrey E. Hundstad]

While booting linux-2.4.27-pre1 the system hangs.  If I put a 20 second 
delay in at the lilo prompt then the system always boot successfully.  
...I just pulled 20 seconds out of the air... less time might work,  but 
I haven't tried.  I've also tried linux-2.4.24 with the same results.

I've since updated the system and raid card to the most current bios. 
and it hasn't helped.  The old raid bios was build 6082.

The system hangs right before the "Red Hat/Apaptec..." line below.

My previous information was a bit in error.  I incorrectly remembered 
where the system would hang.  It hangs in the place indicated below:

It appears that the adapter is slow to respond to commands at this
point.  It's possible that this is related to the firmware cache flush
issue we're aware of.

Can you please follow the instructions at 
http://lists.us.dell.com/pipermail/linux-poweredge/2004-May/020104.html
which describe how to disable the read and write caches using the
afacli command and see if that solves it for you?  If so, then the
permanent solution will be a new firmware when released.

Thanks,
Matt
