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
