Just to be complete, there are already a whole bunch of machines that

to boot 5.x with ACPI on or off, on any of the 5 Dell PowerEdge 6350
servers I have here, even though they run 4.9 perfectly.  I have a PR open
on it.

So even without the ACPI issues on some hardware, there are still other
reasons why 5.x is going to fail to boot.




Are you using a PERC in those boxes? I've seen issues with PERC
controllers on 5.1, but 4.8 worked fine. I received a patch, which
fixed it, but it's a bit hard to install the os, and then rebuild world
without rebooting the machine. :)



Well, there are so many kinds of PERC cards. Some are just Mylex cards. Others are MegaRAID. I think they use some Adaptec now.

My troubles were with the MegaRAID variant, I'm not sure about the others..

Either way, I tried booting the install CD with all cards disconnected,
just to see if I could get the installer up to the main menu. No go. The
display switches off as soon as sysinstall starts probing devices. It
appears to panic, but the display is dead. Once I was able to use
scrolllock at the critical moment just before the kernel starts
sysinstall, and prevent the display from switch off, but when I release
the scroll lock, I was at the DDB prompt. Not good.


First - I hope you mean the cards are physically OUT of the machine - it seemed to me that if they had a logical disk configuration on the card, it would hang. Although, it sounds like your problem is different. Actually, it kind of sounds like it thinks you are doing the "-p" boot thing to check for keyboard and roll over to the serial port. Other than that, I'm out of ideas (doesn't take long for that to happen though!).. :(
