ahd driver on 4.9 has problem with more than 3 drives.

[Pranav Desai]

Hello All,

  I am trying to run FreeBSD 4.9 on a server that has 4x146GB ultra
320 SCSI drives. The motherboard is a Tyan S2720 with an Adaptec 7902
Ultra 320 onboard. (Also tried it with 4x73GB drives).

The systems works fine when there are 3 drives in the system. As, soon
as I plug in the 4th drive and boot the system in starts to 'dump card
state' after the
'waiting for 15 secs for scsi devices to settle' line and never boots
up completely. It just repeats dumps card state.

I then loaded FreeBSD 5.2.1-REL and even that dumps card state, but it
boots up fine.
I have included the dmesg in the mail. (Sorry for including
everything. I didnt know what might be important).

I havent changed anything in the kernel, its a standard install. 

Does anyone have any clue as to why this could be happening on 4.9. Am
I missing some parameter or something here.

Or, is it possible to load the 5.2.1 ahd driver on 4.9. If so can
somebody give some instructions on how to do that.

I would appreciate any kind of help. Please let me know if you want me
to do anything else or provide any other information.

Thanks
-Pranav
